[Kernel-packages] [Bug 1797802] Re: Erratic behavior of CPU frequency control under load
Can you reassign this bug to thermald package? Or should I create a new one?

The other times everything works fine. I don't know what triggers this weird state. Suspend / resume? Maybe. At first I thought this was maybe just a "perception issue", but then when the sluggishness happened again, I fired up i7z and it looks that CPU frequency almost never got over ~1600 MHz, But my CPU is perfectly capable of going up to 4000 MHz! I tried to fix it by setting echo 80 > /sys/devices/system/cpu/intel_pstate/min_perf_pct echo 80 > /sys/devices/system/cpu/intel_pstate/max_perf_pct I hoped I would force the CPU into almost max performance state this way. And indeed, once I ran these commands, i7z showed steady 3100+ MHz on all cores. Then something weird happened - when I run some mild load on the CPU, like just starting the IDE, during the startup the frequency ** dropped back to about 800-1600 MHz ** and returned to 3100 MHz after the load was gone (IDE loaded). The CPU core temperatures shown by sensors / i7z are ok and typically at about 40-50 C when this slowdown happens, so this doesn't look like thermal throttling. Any ideas?

[Kernel-packages] [Bug 1797802] Re: Erratic behavior of intel pstate CPU frequency control
More observations: The problem does not happen if I disable Intel speed-step in BIOS. In this case, the CPU frequency of all cores goes to 2998 MHz whenever under load, and stays stable regardless of how long the load is applied. The problem still happens even if intel_pstate=disable is passed to the kernel on boot. I tried forcing the CPU to its max frequency by using userspace governor and it worked only under idle load (freq ~3.9 GHz). As soon as multi-core load was applied, the CPU frequency dropped to ~1.6 GHz and went back to ~3.9 GHz only when the load was over. I observed a similar pattern when trying to force CPU only to 2.8 GHz - it still slowed down to 1.6 GHz under load, even though temperature should not be a problem in this case. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1797802 Title: Erratic behavior of intel pstate CPU frequency control Status in linux package in Ubuntu: Triaged Bug description: I noticed that sometimes my Ubuntu 18.10 system feels sluggish.

[Kernel-packages] [Bug 1797802] Re: Erratic behavior of intel pstate CPU frequency control
The problem exists in 4.19.rc7 I just tried.
So overall, I'm not sure now if this is a "different state" of the
system, or just a normal behavior of it.
Fresh after boot, the CPU is willing to use frequencies above 3 GHz. The
same when I launch my IDE (IntelliJ idea for the first time). Then when
I hit "rebuild project" to compile all the stuff, the frequency goes up
to 3+ GHz for a short while, and after just 2-4 seconds it drops back to
about 1.3-1.6 GHz and stays at this level for the whole build (several
minutes). The temperatures reported by i7z do not go above 54 C on any
of the cores, and VCore is kept around 0.69 - 0.71.
What does not look right to me are very high numbers reported in the Halt (C1)
column at the same time when C0 column reports numbers > 90. Typically C1
numbers are over 50, and some hit 90+.
This doesn't make much sense to me, because I thought C1 and C0 are distinct
(either/or, the core cannot be in both at the same time).
When the system is loaded by background compilation of my project, the
CPU is not willing to use higher frequencies even when I add more load
to it temporarily.
I compiled a really simple code doing an infinite loop:
int main() {
for (;;);

Now running this program on an idle system makes the CPU frequency go to
about 2.8 GHz. C0 states are reported at less than 5, C1 states for all
cores are > 95 and temperatures are < 53.
Interestingly running this same program when the system is compiling in
background does not increase the frequencies above 1.6 GHz. If it is
loaded, it is unwilling to go faster. :D
So to summarize the CPU is capable to use higher frequencies for a very
short span of time, but then the performance quickly degrades under load
and stays there.

Title:
Erratic behavior of intel pstate CPU frequency control
Status in linux package in Ubuntu:
Incomplete
Bug description:
I noticed that sometimes my Ubuntu 18.10 system feels sluggish. The
other times everything works fine. I don't know what triggers this
weird state. Suspend / resume? Maybe.
At first I thought this was maybe just a "perception issue", but then
when the sluggishness happened again, I fired up i7z and it looks that
CPU frequency almost never got over ~1600 MHz, But my CPU is perfectly
capable of going up to 4000 MHz!
I tried to fix it by setting
echo 80 > /sys/devices/system/cpu/intel_pstate/min_perf_pct
echo 80 > /sys/devices/system/cpu/intel_pstate/max_perf_pct
I hoped I would force the CPU into almost max performance state this
way. And indeed, once I ran these commands, i7z showed steady 3100+
MHz on all cores.
Then something weird happened - when I run some mild load on the CPU,
like just starting the IDE, during the startup the frequency **
dropped back to about 800-1600 MHz ** and returned to 3100 MHz after
the load was gone (IDE loaded).
The CPU core temperatures shown by sensors / i7z are ok and typically
at about 40-50 C when this slowdown happens, so this doesn't look like
thermal throttling.
Any ideas?

[Kernel-packages] [Bug 1797802] Re: Erratic behavior of intel pstate CPU frequency control
Is it normal that C-states percentages reported by i7z don't sum up to 100%, but exceed it? Under load, I frequently get C0% close to 99%, but at the same time Halt is at about 40-60%. Also when C0 is >90, the frequency of cores goes DOWN.

[Kernel-packages] [Bug 1797802] [NEW] Erratic behavior of intel pstate CPU frequency control
Public bug reported: I noticed that sometimes my Ubuntu 18.10 system feels sluggish. The other times everything works fine. I don't know what triggers this weird state. Suspend / resume? Maybe. At first I thought this was maybe just a "perception issue", but then when the sluggishness happened again, I fired up i7z and it looks that CPU frequency almost never got over ~1600 MHz, But my CPU is perfectly capable of going up to 4000 MHz! I tried to fix it by setting echo 80 > /sys/devices/system/cpu/intel_pstate/min_perf_pct echo 80 > /sys/devices/system/cpu/intel_pstate/max_perf_pct I hoped I would force the CPU into almost max performance state this way. And indeed, once I ran these commands, i7z showed steady 3100+ MHz on all cores. Then something weird happened - when I run some mild load on the CPU, like just starting the IDE, during the startup the frequency ** dropped back to about 800-1600 MHz ** and returned to 3100 MHz after the load was gone (IDE loaded).

[Kernel-packages] [Bug 1701499] Re: System often freezes or panics if I log in with Dell Dock WD15 connected
Unfortunately I no longer have the WD15 dock. I switched to TB16 and it also has some hotplugging issue (there is a separate launchpad ticket reported by others). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701499 Title: System often freezes or panics if I log in with Dell Dock WD15 connected Status in linux package in Ubuntu: Confirmed Bug description: I'm using Dell Precision 5520 with Ubuntu 17.04. If I first start a Unity session and then connect Dell WD15 USB-C dock with an external diplay plugged in, the system detects it properly and all the things work flawlessly (ethernet, external keyboard, external display, external storage connected to USB on the dock). I can plug-in and plug-out the dock multiple times and it just works. However if I boot the laptop with the dock already plugged in, first I get to the login screen and initially all is ok. Both screens are activated, and I can log in using the keyboard connected to the dock. When I hit "Enter", both screens go blank for a while, then they turn back on and I can see the desktop. A second or maybe two seconds later things start falling apart. When I move the mouse pointer a second after logging, it is kinda "jumpy", the movement is not smooth. The move freezes for a few times. I observed this behaviour only when moving the wireless mouse connected to the USB of the laptop. The builtin touchpad works smoothly. If it was the only issue, this would be a very minor annoyance. Sometimes, after a few short mouse pointer freezes the system starts working smoothly and all is rock stable from that point. However quite often I noticed much worse things happen: 1. The mouse pointer and everything freezes totally after a few seconds from displaying the desktop. It is not possible to switch to the console with Ctrl-Alt-F1. This happens in >50% of logins. 2. Kernel panic. I observed this behavior with stable Ubuntu kernel 4.10.0-20, as well as 4.11.0 - 4.11.8 (which I'm using now, because 4.11.x seems more stable than 4.10.0-x) and also 4.12.rc5 which I tried once.

After a week of testing v4.14-rc2, the conclusions remain the same: - System doesn't freeze when booting up and logging in with the dock attached. - Ethernet doesn't connect automatically on boot / after login, manual intervention required. - System doesn't wake from suspend if the dock was disconnected during sleep. - System does wake properly from suspend if the dock was connected during sleep or dock connection did not change at all. - No sudden ethernet disconnects. I've got also a TB16 dock now: Problems with kernel 4.13.4: - Graphics crash when booting with dock attached, Ubuntu displayed a message asking what to do, but it recovered after selecting low res mode. Interestingly, I managed to log into desktop. - Everything else same as with WD15 dock. Kernel v4.14.rc2: same behavior as with v4.14.rc2 + WD15 dock. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701499 Title: System often freezes or panics if I log in with Dell Dock WD15 connected Status in linux package in Ubuntu: Confirmed Bug description: I'm using Dell Precision 5520 with Ubuntu 17.04. If I first start a Unity session and then connect Dell WD15 USB-C dock with an external diplay plugged in, the system detects it properly and all the things work flawlessly (ethernet, external keyboard, external display, external storage connected to USB on the dock). I can plug-in and plug-out the dock multiple times and it just works. However if I boot the laptop with the dock already plugged in, first I get to the login screen and initially all is ok. Both screens are activated, and I can log in using the keyboard connected to the dock. When I hit "Enter", both screens go blank for a while, then they turn back on and I can see the desktop.

If it was the only issue, this would be a very minor annoyance. Sometimes, after a few short mouse pointer freezes the system starts working smoothly and all is rock stable from that point. However quite often I noticed much worse things happen: 1. The mouse pointer and everything freezes totally after a few seconds from displaying the desktop.

No, after disabling apparmor for dhclient, I'm successfully running v4.14-rc2. However, it looks like exactly the same problems exist with this kernel as with v4.14-rc2: 1. NetworkManager fails to connect automatically at startup, but connects fine after manual intervention. 2. System fails to resume if it was disconnected from the dock while suspended. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701499 Title: System often freezes or panics if I log in with Dell Dock WD15 connected Status in linux package in Ubuntu: Confirmed Bug description: I'm using Dell Precision 5520 with Ubuntu 17.04.

[Kernel-packages] [Bug 1701499] Re: System often freezes or panics if I log in with Dell Dock WD15 connected
Still using 4.13.3 today and I already had sudden ethernet connection dropout which couldn't be reestabliished from NetworkManager without replugging the dock. I conclude this problem must be related to kernel then, because as said earlier, on 4.14.rc1 I had no ethernet stability issues for the whole week (besides having to manually establish it after logging). I have pretty high hopes for 4.14.x then as it seems to fix the two most serious issues. What a pity that 4.14.rc2 doesn't work for me at all :( -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701499 Title: System often freezes or panics if I log in with Dell Dock WD15 connected Status in linux package in Ubuntu: Confirmed Bug description: I'm using Dell Precision 5520 with Ubuntu 17.04. If I first start a Unity session and then connect Dell WD15 USB-C dock with an external diplay plugged in, the system detects it properly and all the things work flawlessly (ethernet, external keyboard, external display, external storage connected to USB on the dock). I can plug-in and plug-out the dock multiple times and it just works. However if I boot the laptop with the dock already plugged in, first I get to the login screen and initially all is ok.

I also checked 4.13.3 a moment ago and when booting with the dock attached I got a freeze again soon after starting the desktop session. So the original bug I reported here was definitely not fixed in 4.13.3, nor by BIOS upgrade to 1.5.0. However, all network connections were active at the login screen. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701499 Title: System often freezes or panics if I log in with Dell Dock WD15 connected Status in linux package in Ubuntu: Confirmed Bug description: I'm using Dell Precision 5520 with Ubuntu 17.04.

[Kernel-packages] [Bug 1701499] Re: System often freezes or panics if I log in with Dell Dock WD15 connected
I was running v4.14-rc1 for the whole last week. It is... different. Good stuff: - Not a single freeze on fresh boot with dock attached. - When it connects to eth0, it is stable. Not a single disconnect from ethernet, but that may be as well the result of recent BIOS upgrade to 1.5.0 and dock firmware update that I did at about the time I upgraded to v4.14-rc1. - Suspend / resume stable, as long as I don't connect/disconnect the dock in the meantime. Slightly broken stuff: - Ethernet connection does not come up automatically after boot / login. Syslog shows the eth0 device exists, NetworkManager attempts to connect, it even gets the IP from DHCP, then it suddenly disconnects. I have to manually click in the NetworkManager icon to connect after logging into desktop and suprisingly it connects fine.

I upgraded to BIOS 1.5.0 yesterday and also upgraded the dock firmware yesterday as well again (using windows-10-on-the-go usb stick I created just for that purpose). No improvements - I got a nice freeze on boot again (kernel 4.12.13). Also, Windows 10 seems to be working on the same hardware just fine; no freezes when booting with the dock plugged in, neither when hotplugging. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701499 Title: System often freezes or panics if I log in with Dell Dock WD15 connected Status in linux package in Ubuntu: Confirmed Bug description: I'm using Dell Precision 5520 with Ubuntu 17.04.

[Kernel-packages] [Bug 1701499] Re: System often freezes or panics if I log in with Dell Dock WD15 connected
Unfortunately that turned out to be a fluke. I had two freezes on 4.11.12, and just a freeze a minute ago on fresh 4.13.rc3 installed from http://kernel.ubuntu.com/~kernel-ppa/mainline/. No panics though. I noticed all these freezes have a few things in common: - they happen only when the dock is plugged in during logging into Ubuntu session; they don't happen if I plug in the dock after logging in. - they happen AFTER the ethernet connection through the dock is dropped and BEFORE it is reestablished after login - when the freeze happens, the network manager shows I have only wifi connection. If the system goes past reestablishing ethernet connection through the dock, everything works smoothly. Also suspend/resume with the dock connected is fine. Additionally, the dock seems to operate properly before I login. I never ever had a panic or freeze before logging into my account. The network manager icon shows the ethernet connection is active at the login screen. However, this connection is dropped immediately after logging in (why?) and re-established. I also noticed some rare instabilities in ethernet connectivity - sometimes it just drops the connection in the middle of the day and needs replugging (reconnecting from network manager doesn't work in this case). BTW: I updated the dock firmware to the most recent version from Dell. I had to use Windows for that. But this didn't help. ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701499 Title: System often freezes or panics if I log in with Dell Dock WD15 connected Status in linux package in Ubuntu: Confirmed Bug description: I'm using Dell Precision 5520 with Ubuntu 17.04.

Yesterday I updated to 4.11.9 and so far everything is stable. I managed to reboot 6 times in a row with no issues. The kernel error is also gone from syslog. I'm still not totally sure, because the original issue is a bit random, so that might have been just a good luck. The jumpiness of mouse pointer shortly after connecting the dock remained, but this is a very minor issue (and might not be related to the freeze / panic problems). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701499 Title: System often freezes or panics if I log in with Dell Dock WD15 connected Status in linux package in Ubuntu: Incomplete Bug description: I'm using Dell Precision 5520 with Ubuntu 17.04.

[Kernel-packages] [Bug 1701499] [NEW] System often freezes or panics if I log in with Dell Dock WD15 connected
Public bug reported: I'm using Dell Precision 5520 with Ubuntu 17.04. If I first start a Unity session and then connect Dell WD15 USB-C dock with an external diplay plugged in, the system detects it properly and all the things work flawlessly (ethernet, external keyboard, external display, external storage connected to USB on the dock). I can plug-in and plug-out the dock multiple times and it just works. However if I boot the laptop with the dock already plugged in, first I get to the login screen and initially all is ok. Both screens are activated, and I can log in using the keyboard connected to the dock. When I hit "Enter", both screens go blank for a while, then they turn back on and I can see the desktop. A second or maybe two seconds later things start falling apart. When I move the mouse pointer a second after logging, it is kinda "jumpy", the movement is not smooth. The move freezes for a few times. I observed this behaviour only when moving the wireless mouse connected to the USB of the laptop. The builtin touchpad works smoothly. If it was the only issue, this would be a very minor annoyance. Sometimes, after a few short mouse pointer freezes the system starts working smoothly and all is rock stable from that point. However quite often I noticed much worse things happen: 1. The mouse pointer and everything freezes totally after a few seconds from displaying the desktop. It is not possible to switch to the console with Ctrl-Alt-F1. This happens in >50% of logins. 2. Kernel panic. I observed this behavior with stable Ubuntu kernel 4.10.0-20, as well as 4.11.0 - 4.11.8 (which I'm using now, because 4.11.x seems more stable than 4.10.0-x) and also 4.12.rc5 which I tried once.

If I first start a Unity session and then connect Dell WD15 USB-C dock with an external diplay plugged in, the system detects it properly and all the things work flawlessly (ethernet, external keyboard, external display, external storage connected to USB on the dock). I can plug-in and plug-out the dock multiple times and it just works. However if I boot the laptop with the dock already plugged in, first I get to the login screen and initially all is ok. Both screens are activated, and I can log in using the keyboard connected to the dock. When I hit "Enter", both screens go blank for a while, then they turn back on and I can see the desktop. A second or maybe two seconds later things start falling apart. When I move the mouse pointer a second after logging, it is kinda "jumpy", the movement is not smooth. The move freezes for a few times. I observed this behaviour only when moving the wireless mouse connected to the USB of the laptop. The builtin touchpad works smoothly. If it was the only issue, this would be a very minor annoyance. Sometimes, after a few short mouse pointer freezes the system starts working smoothly and all is rock stable from that point. However quite often I noticed much worse things happen: 1. The mouse pointer and everything freezes totally after a few seconds from displaying the desktop. It is not possible to switch to the console with Ctrl-Alt-F1. This happens in >50% of logins. 2. Kernel panic. I observed this behavior with stable Ubuntu kernel 4.10.0-20, as well as 4.11.0 - 4.11.8 (which I'm using now, because 4.11.x seems more stable than 4.10.0-x) and also 4.12.rc5 which I tried once.
