[Kernel-packages] [Bug 1852001] Re: KDE GUI freeze on high disk IO

@ccheney
Do you have any new information on this bug? Did your trick with drop_caches 
work eventually?
I'm experiencing the same issue for quite some time with both KDE and Gnome (to 
support the fact that it's DE agnostic) and it definitely seems to occur at 
times when system starts caching. The GUI becomes completely unresponsive 
(including the mouse pointer) and the io indicator on laptop blinks violently. 
Each time this happens I make sure to check and confirm that the amount of 
swapped data is significant enough (from half a gigabyte to couple of gigabytes)

Title:
  KDE GUI freeze on high disk IO

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've got massive problems with GUI on my PC.

  The attached logs are from the following setting: 
  - high disk load (f3write)
  - kernel 4.15.0-1050-oem (the only 4x kernel available in eoan)
  - no swap available

  These are the parameters (disk load, kernel, swap) I am fiddling with
  to find out the cause, see below.

  In general 
  - the problem happens once a day with any 5.0 or 5.3 kernel from eoan repo
  - more likely to happen with high disk or CPU load, but not necessarily.
  - less likely with the 4.x kernel mentioned above. 

  I just installed the following kernels from kernel-ppa:
  5.3.10-050310-generic 
  5.4.0-050400rc6-generic
  5.4.0-997-generic (drm-intel-next)
  Now I am waiting for the freeze to occur again. 

  The problem started about half a year ago. 
  There have been three changes that happened at the time and could be the cause
  - switch to kernel 5.x
  - update to Ubuntu 19.4
  - swapped motherboard, CPU and RAM. 

  The hassle started with the following scenario, repeated often: 
  - high disk load
  - PC becomes laggy
  - soon dies/freezes

  The longer I waited, the deeper the lockdown went. but I don't know the exact 
details. 
  The first cause I found was kswapd running amok and take the system with it. 
Workaround: add swap space. 

  Now the problem shifted: Whenever I got high disk load (eg dd 100 GB
  of data) the kernel swaps likle crazy and makes the GUI first lag soon
  freeze. but no excessive CPU load any more, as kswapd does not go
  crazy.

  Again I found a workaround: 
  the above mentioned 4.x kernel. In this case the GUI lags as expected from a 
heavily swapping system. nothing more. 
  but still sometimes the GUI simply freezes (the error reported at the top)

  Another workaround is to completely remove swap. Let's see what
  happens, if kswapd goes amok again.

  I am not sure as how these problems are related.

  I did extensive hardware check like
  - memtest86 newest version, no "may be vulnerable to high frequency row 
hammering"
  - smart

  do you suggest any burn in test suites?

  thanks

2020-08-02 Thread JPT
@ccheney
Regardless if my crashes are gone, my experience is that having a swap file in 
recent Linux is deadly. If Linux starts swapping only a little then it's hardly 
usable any more. I believe this is because of the algorithm that decides which 
pages to remove from memory. 

Your observation with 50% RAM could be related to VMLIM. VMLIM says how
much of the RAM may be used for programs. By default this is half your
RAM. The other half is for cache and buff only. (as I understood, this
may be inaccurate). Try other values for VMLIM.

Actually looking at the patch (shrink_dcache_for_umount) this might not
be the whole problem but may be just related. The problem I am having is
while the system is still running, and cache growing huge, not while
umounting.

Title:
  KDE GUI freeze on high disk IO

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've got massive problems with GUI on my PC.

  The attached logs are from the following setting: 
  - high disk load (f3write)
  - kernel 4.15.0-1050-oem (the only 4x kernel available in eoan)
  - no swap available

  These are the parameters (disk load, kernel, swap) I am fiddling with
  to find out the cause, see below.

  In general 
  - the problem happens once a day with any 5.0 or 5.3 kernel from eoan repo
  - more likely to happen with high disk or CPU load, but not necessarily.
  - less likely with the 4.x kernel mentioned above. 

  I just installed the following kernels from kernel-ppa:
  5.3.10-050310-generic 
  5.4.0-050400rc6-generic
  5.4.0-997-generic (drm-intel-next)
  Now I am waiting for the freeze to occur again. 

  The problem started about half a year ago. 
  There have been three changes that happened at the time and could be the cause
  - switch to kernel 5.x
  - update to Ubuntu 19.4
  - swapped motherboard, CPU and RAM. 

  The hassle started with the following scenario, repeated often: 
  - high disk load
  - PC becomes laggy
  - soon dies/freezes

  The longer I waited, the deeper the lockdown went. but I don't know the exact 
details. 
  The first cause I found was kswapd running amok and take the system with it. 
Workaround: add swap space. 

  Now the problem shifted: Whenever I got high disk load (eg dd 100 GB
  of data) the kernel swaps likle crazy and makes the GUI first lag soon
  freeze. but no excessive CPU load any more, as kswapd does not go
  crazy.

  Again I found a workaround: 
  the above mentioned 4.x kernel. In this case the GUI lags as expected from a 
heavily swapping system. nothing more. 
  but still sometimes the GUI simply freezes (the error reported at the top)

  Another workaround is to completely remove swap. Let's see what
  happens, if kswapd goes amok again.

  I am not sure as how these problems are related.

  I did extensive hardware check like
  - memtest86 newest version, no "may be vulnerable to high frequency row 
hammering"
  - smart

  do you suggest any burn in test suites?

  thanks

[Kernel-packages] [Bug 1852001] Re: KDE GUI freeze on high disk IO

2020-07-31 Thread Chris Cheney
I haven't verified if this actually fixes the problem but it seems to
make a huge difference in 'free' memory as shown by 'free'.

I had already closed my VMs by the time I tried this so haven't verified
if it stops the long freezes yet.

  totalusedfree  shared  buff/cache   available
Mem:  31030533127905347   22907   19900
Swap: 327673130   29637

echo 3 > /proc/sys/vm/drop_caches

  totalusedfree  shared  buff/cache   available
Mem:  310305349   1712253128557   19915
Swap: 327673130   29637

Notice the 2790 -> 17122 change above in 'free', and 22907 -> 8557 for
buff/cache.

It appears the kernel doesn't get rid of cache in a reasonable timeframe
at the expense of swapping programs out to disk while i/o is happening,
which causes gui freezes.

[Kernel-packages] [Bug 1852001] Re: KDE GUI freeze on high disk IO

2020-07-31 Thread Chris Cheney
I have this problem as well on Cinnamon, so it doesn't appear to be
specific to KDE. It stalls often and frequently over 15-30 seconds at a
time for no apparent reason. But the swapping to disk may be a clue.

I see this on 5.4.0-40 and have also tried with the lowlatency version
of the kernel and it doesn't help.

One thing that seems to reduce the frequency of the problem somewhat is
to disable transparent_hugepage support but it still happens even after
that.

I have 32GB ram and it starts happening when I get to about 50% ram (mem
available) usage. The system also appears to start swapping at that
point despite what swappiness is set to. I tried setting it to 10 but it
is still swapping at what appears to be ~ 50% usage.

It appears to be very easy to reproduce if you run a few VMware VMs on a
system.

  The hassle started with the following scenario, repeated often: 
  - high disk load
  - PC becomes laggy
  - soon dies/freezes

  The longer I waited, the deeper the lockdown went. but I don't know the exact 
details. 
  The first cause I found was kswapd running amok and take the system with it. 
Workaround: add swap space. 

  Now the problem shifted: Whenever I got high disk load (eg dd 100 GB
  of data) the kernel swaps likle crazy and makes the GUI first lag soon
  freeze. but no excessive CPU load any more, as kswapd does not go
  crazy.

  Again I found a workaround: 
  the above mentioned 4.x kernel. In this case the GUI lags as expected from a 
heavily swapping system. nothing more. 
  but still sometimes the GUI simply freezes (the error reported at the top)

  Another workaround is to completely remove swap. Let's see what
  happens, if kswapd goes amok again.

  I am not sure as how these problems are related.

  I did extensive hardware check like
  - memtest86 newest version, no "may be vulnerable to high frequency row 
hammering"
  - smart

  do you suggest any burn in test suites?

  thanks

[Kernel-packages] [Bug 1852001] Re: KDE GUI freeze on high disk IO

2020-07-20 Thread JPT
Probably fucked up installation was the cause of this. sorry for
bothering.

I recently reinstalled Kubuntu because I was frustrated with the stability of 
my system. It still hadn't really improved since switch to kernel 5.4
And, magically, all the crashes are gone. So, no idea why but something in my 
old system seems to have caused most of the crashes.

Title:
  KDE GUI freeze on high disk IO

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've got massive problems with GUI on my PC.

  The attached logs are from the following setting: 
  - high disk load (f3write)
  - kernel 4.15.0-1050-oem (the only 4x kernel available in eoan)
  - no swap available

  These are the parameters (disk load, kernel, swap) I am fiddling with
  to find out the cause, see below.

  In general 
  - the problem happens once a day with any 5.0 or 5.3 kernel from eoan repo
  - more likely to happen with high disk or CPU load, but not necessarily.
  - less likely with the 4.x kernel mentioned above. 

  I just installed the following kernels from kernel-ppa:
  5.3.10-050310-generic 
  5.4.0-050400rc6-generic
  5.4.0-997-generic (drm-intel-next)
  Now I am waiting for the freeze to occur again. 

  The problem started about half a year ago. 
  There have been three changes that happened at the time and could be the cause
  - switch to kernel 5.x
  - update to Ubuntu 19.4
  - swapped motherboard, CPU and RAM. 

  The hassle started with the following scenario, repeated often: 
  - high disk load
  - PC becomes laggy
  - soon dies/freezes

  The longer I waited, the deeper the lockdown went. but I don't know the exact 
details.

I have a feeling based on experience with multiple machines running
gnome-shell that this issue was specific to kernel 5.3 and has gone away
in 5.4 and later.

Title:
  KDE GUI freeze on high disk IO

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I've got massive problems with GUI on my PC.

  The attached logs are from the following setting: 
  - high disk load (f3write)
  - kernel 4.15.0-1050-oem (the only 4x kernel available in eoan)
  - no swap available

  These are the parameters (disk load, kernel, swap) I am fiddling with
  to find out the cause, see below.

  In general 
  - the problem happens once a day with any 5.0 or 5.3 kernel from eoan repo
  - more likely to happen with high disk or CPU load, but not necessarily.
  - less likely with the 4.x kernel mentioned above. 

  I just installed the following kernels from kernel-ppa:
  5.3.10-050310-generic 
  5.4.0-050400rc6-generic
  5.4.0-997-generic (drm-intel-next)
  Now I am waiting for the freeze to occur again. 

  The problem started about half a year ago. 
  There have been three changes that happened at the time and could be the cause
  - switch to kernel 5.x
  - update to Ubuntu 19.4
  - swapped motherboard, CPU and RAM. 

  The hassle started with the following scenario, repeated often: 
  - high disk load
  - PC becomes laggy
  - soon dies/freezes

  The longer I waited, the deeper the lockdown went. but I don't know the exact 
details. 
  The first cause I found was kswapd running amok and take the system with it. 
Workaround: add swap space. 

  Now the problem shifted: Whenever I got high disk load (eg dd 100 GB
  of data) the kernel swaps likle crazy and makes the GUI first lag soon
  freeze. but no excessive CPU load any more, as kswapd does not go
  crazy.

[Kernel-packages] [Bug 1852001] Re: KDE GUI freeze on high disk IO

2020-02-05 Thread JPT
Still this bugs haunts me every day.

kernel 5.3.0-29-generic still affected.

whenever swap is enabled, the system is almost unusable when cache grows
too large with time. as already told, this is by far worse than the
infamous linux swap trashing.

while this can be worked around easily, I am still logged out without any 
warning randomly about every day, killing all active programs. 
This seems a bit more likely when I have Windows Virtualboxes running, that 
have more than one processor core assigned. I already updated VB-Client, 
VB-Settings...

my assumption: this is some threading issue. maybe wrong priority of
some graphics stuff, maybe too many semaphores in swap-in code... I
don't know.

This problem annoys me for almost a year now. I give up. 
My last try is making Virtualbox work with the testing kernels. 
If this doesn't work I will try some other distribution.

I think more likely it was a kernel bug and we just haven't bisected it
clearly yet. Try going back to a v5.3 kernel like Ubuntu is shipping and
see if it happens there?

2019-12-18 Thread JPT
Haven't had a problem for over a week now with kernel 5.4.1-050401-generic.
Strange, as a comment above says it happened with this kernel as well. 

So it probably was fixed by the Firefox update?

updates since Dec 8th contain: 
- Firefox from 69.0.3 to 71.0
- Thunderbird
- samba, git, wine, ssh, makemkv

Title:
  KDE GUI freeze on high disk IO

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I've got massive problems with GUI on my PC.

  The attached logs are from the following setting: 
  - high disk load (f3write)
  - kernel 4.15.0-1050-oem (the only 4x kernel available in eoan)
  - no swap available

  These are the parameters (disk load, kernel, swap) I am fiddling with
  to find out the cause, see below.

  In general 
  - the problem happens once a day with any 5.0 or 5.3 kernel from eoan repo
  - more likely to happen with high disk or CPU load, but not necessarily.
  - less likely with the 4.x kernel mentioned above. 

  I just installed the following kernels from kernel-ppa:
  5.3.10-050310-generic 
  5.4.0-050400rc6-generic
  5.4.0-997-generic (drm-intel-next)
  Now I am waiting for the freeze to occur again. 

  The problem started about half a year ago. 
  There have been three changes that happened at the time and could be the cause
  - switch to kernel 5.x
  - update to Ubuntu 19.4
  - swapped motherboard, CPU and RAM. 

  The hassle started with the following scenario, repeated often: 
  - high disk load
  - PC becomes laggy
  - soon dies/freezes

  The longer I waited, the deeper the lockdown went. but I don't know the exact 
details. 
  The first cause I found was kswapd running amok and take the system with it. 
Workaround: add swap space. 

  Now the problem shifted: Whenever I got high disk load (eg dd 100 GB
  of data) the kernel swaps likle crazy and makes the GUI first lag soon
  freeze. but no excessive CPU load any more, as kswapd does not go
  crazy.

  Again I found a workaround: 
  the above mentioned 4.x kernel. In this case the GUI lags as expected from a 
heavily swapping system. nothing more. 
  but still sometimes the GUI simply freezes (the error reported at the top)

  Another workaround is to completely remove swap. Let's see what
  happens, if kswapd goes amok again.

  I am not sure as how these problems are related.

  I did extensive hardware check like
  - memtest86 newest version, no "may be vulnerable to high frequency row 
hammering"
  - smart

  do you suggest any burn in test suites?

  thanks

2019-12-11 Thread JPT
There is for sure a bug. 
As I said, I know how a system behaves that is suffering from too much swapping.

My case is far worse.

and still, about once a day the GUI is completely locked. this cannot be
explained from swapping and cannot be solved by disabling swap.

I think the only kernel yet that did not suffer was

[Kernel-packages] [Bug 1852001] Re: KDE GUI freeze on high disk IO, but disabling swap fixes it

2019-12-11 Thread Kai-Heng Feng
According to the description there's no swap in the end, so I think it's
like discussion in [1]. So yes, I think it's still a kernel bug.

For desktop usage, [2] [3] are mentioned by dsd in the discussion. Maybe
we can adopt those daemon as an OOM killer for desktops.

Title:
  KDE GUI freeze on high disk IO, but disabling swap fixes it

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've got massive problems with GUI on my PC.

  The attached logs are from the following setting: 
  - high disk load (f3write)
  - kernel 4.15.0-1050-oem (the only 4x kernel available in eoan)
  - no swap available

  These are the parameters (disk load, kernel, swap) I am fiddling with
  to find out the cause, see below.

  In general 
  - the problem happens once a day with any 5.0 or 5.3 kernel from eoan repo
  - more likely to happen with high disk or CPU load, but not necessarily.
  - less likely with the 4.x kernel mentioned above. 

  I just installed the following kernels from kernel-ppa:
  5.3.10-050310-generic 
  5.4.0-050400rc6-generic
  5.4.0-997-generic (drm-intel-next)
  Now I am waiting for the freeze to occur again. 

  The problem started about half a year ago. 
  There have been three changes that happened at the time and could be the cause
  - switch to kernel 5.x
  - update to Ubuntu 19.4
  - swapped motherboard, CPU and RAM. 

  The hassle started with the following scenario, repeated often: 
  - high disk load
  - PC becomes laggy
  - soon dies/freezes

  The longer I waited, the deeper the lockdown went. but I don't know the exact 
details. 
  The first cause I found was kswapd running amok and take the system with it. 
Workaround: add swap space. 

  Now the problem shifted: Whenever I got high disk load (eg dd 100 GB
  of data) the kernel swaps likle crazy and makes the GUI first lag soon
  freeze. but no excessive CPU load any more, as kswapd does not go
  crazy.

  Again I found a workaround: 
  the above mentioned 4.x kernel. In this case the GUI lags as expected from a 
heavily swapping system. nothing more. 
  but still sometimes the GUI simply freezes (the error reported at the top)

  Another workaround is to completely remove swap. Let's see what
  happens, if kswapd goes amok again.

  I am not sure as how these problems are related.

  I did extensive hardware check like
  - memtest86 newest version, no "may be vulnerable to high frequency row 
hammering"
  - smart

  do you suggest any burn in test suites?

  thanks

[Kernel-packages] [Bug 1852001] Re: KDE GUI freeze on high disk IO, but disabling swap fixes it

2019-12-10 Thread Daniel van Vugt
I'm not really sure this is a bug. It sounds like expected behaviour:

1. Disk gets thrashed.
2. Any processes relying on memory swapping to/from that disk get delayed.

No particular process is doing anything wrong. Just if you want to avoid
that situation then maybe don't configure swap on such a disk.

Then if you can survive without swap, problem solved. If you still need
swapping for other reasons then either do so on a different disk or add
more RAM, or run fewer programs.

I don't think there's any bug here(?)

[Kernel-packages] [Bug 1852001] Re: KDE GUI freeze on high disk IO, but disabling swap fixes it

2019-12-08 Thread JPT
attached "ps auxw" while GUI was freezed. 
kernel 5.4.1-050401-generic
no swap
I restarted GUI using /etc/init.d/sddm restart
right now only the KDE taskbar and menu are locked, Alt-Tab and programs still 
work. (this is a rather new phenomena)
I already experienced this once, where some programs were freezed too (eg 
libreoffice) and others weren't. I only got a message like "program does not 
answer, force close it"?
maybe this is a second hand problem as some inter-process communication locks 
apps when KDE is locked?

after about 5 minutes KDE bar crashed and restarted. now works.

from syslog while KDE bar locked:
pulseaudio[30539]: E: [pulseaudio] bluez5-util.c: GetManagedObjects() failed: 
org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes

Title:
  KDE GUI freeze on high disk IO, but disabling swap fixes it

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I've got massive problems with GUI on my PC.

  The attached logs are from the following setting: 
  - high disk load (f3write)
  - kernel 4.15.0-1050-oem (the only 4x kernel available in eoan)
  - no swap available

  These are the parameters (disk load, kernel, swap) I am fiddling with
  to find out the cause, see below.

  In general 
  - the problem happens once a day with any 5.0 or 5.3 kernel from eoan repo
  - more likely to happen with high disk or CPU load, but not necessarily.
  - less likely with the 4.x kernel mentioned above. 

  I just installed the following kernels from kernel-ppa:
  5.3.10-050310-generic 
  5.4.0-050400rc6-generic
  5.4.0-997-generic (drm-intel-next)
  Now I am waiting for the freeze to occur again. 

  The problem started about half a year ago. 
  There have been three changes that happened at the time and could be the cause
  - switch to kernel 5.x
  - update to Ubuntu 19.4
  - swapped motherboard, CPU and RAM. 

  The hassle started with the following scenario, repeated often: 
  - high disk load
  - PC becomes laggy
  - soon dies/freezes

  The longer I waited, the deeper the lockdown went. but I don't know the exact 
details. 
  The first cause I found was kswapd running amok and take the system with it. 
Workaround: add swap space. 

  Now the problem shifted: Whenever I got high disk load (eg dd 100 GB
  of data) the kernel swaps likle crazy and makes the GUI first lag soon
  freeze. but no excessive CPU load any more, as kswapd does not go
  crazy.

  Again I found a workaround: 
  the above mentioned 4.x kernel. In this case the GUI lags as expected from a 
heavily swapping system. nothing more. 
  but still sometimes the GUI simply freezes (the error reported at the top)

  Another workaround is to completely remove swap. Let's see what
  happens, if kswapd goes amok again.

  I am not sure as how these problems are related.

  I did extensive hardware check like
  - memtest86 newest version, no "may be vulnerable to high frequency row 
hammering"
  - smart

  do you suggest any burn in test suites?

  thanks
