[Kernel-packages] [Bug 2061091] Re: Freezing user space processes failed after 20.008 seconds (1 tasks refusing to freeze, wq_busy=0)

2024-05-01 Thread Richard van der Hoff
Seems I was mistaken. This happens on 6.8 as well.

  Another point of interest is that, when in this situation:
   * `lsusb` hangs after printing out a few lines
   * Outgoing SSH connections hang unless I clear SSH_AUTH_SOCK. gpg-agent 
appears to be trying to check for smartcards.

  So I guess there is some sort of deadlock in the USB subsystem which
  is causing all the other problems?

[Kernel-packages] [Bug 2061091] Re: Freezing user space processes failed after 20.008 seconds (1 tasks refusing to freeze, wq_busy=0)

2024-04-29 Thread Richard van der Hoff
Ok, I reproduced this on a rebuild of 6.5.0-34 with
CONFIG_PROVE_LOCKING. Here are some relevant-looking bits of the logs.
It looks like the wireplumber process and the usb_disconnect process
have deadlocked?

[Thinking about this further, possibly the action that triggers it is to
disconnect the dock while the system is suspended, then resume the
system.]

[Kernel-packages] [Bug 2061091] Re: Freezing user space processes failed after 20.008 seconds (1 tasks refusing to freeze, wq_busy=0)

2024-04-25 Thread Richard van der Hoff
Oddly, I don't seem to be able to reproduce this problem on an upstream
6.8 kernel. I'll try with a rebuild of 6.5.0-27-generic instead.

   * `lsusb` hangs after printing out a few lines
   * Outgoing SSH connections hang unless I clear SSH_AUTH_SOCK. gpg-agent 
appears to be trying to check for smartcards.

  So I guess there is some sort of deadlock in the USB subsystem which
  is causing all the other problems?

[Kernel-packages] [Bug 2061091] Re: Freezing user space processes failed after 20.008 seconds (1 tasks refusing to freeze, wq_busy=0)

2024-04-17 Thread Richard van der Hoff
> And this call trace looks is related to current issue, I guess
snd_power_ref_and_wait was waiting for snd_card_disconnect which wakes
up power_sleep at the end of the code, but snd_card_disconnect ->
snd_device_disconnect_all -> snd_pcm_dev_disconnect was blocked for some
reason.

Yes, interesting. Good spot.

> Looks suspend/resume can be completed sometimes.

Yes. I think what causes the problem is when I disconnect from my USB
dock. After that, I can't suspend until I reboot. Once I reboot, it can
suspend again until I once more disconnect the dock.

Sure. I'll try an upstream kernel with CONFIG_PROVE_LOCKING.

I found a very similar report at
https://discussion.fedoraproject.org/t/freezing-user-space-processes-
failed-after-20-000-seconds-2-tasks-refusing-to-freeze-wq-busy-0/92672,
but no resolution there.

  Freezing user space processes failed after 20.008 seconds (1 tasks

Bug description:
  Sometimes, when trying to shut down or suspend my laptop, it gets

  Another point of interest is that, when in this situation:
   * `lsusb` hangs after printing out a few lines
   * Outgoing SSH connections hang unless I clear SSH_AUTH_SOCK. gpg-agent 
appears to be trying to check for smartcards.

  So I guess there is some sort of deadlock in the USB subsystem which
  is causing all the other problems?

[Kernel-packages] [Bug 1992362] [NEW] USB stops responding on XPS9320

2022-10-10 Thread Richard van der Hoff
Public bug reported:

An intermittent problem, but to reproduce:
 * unplug a USB device
 * plug it back in
 * notice it hasn't been detected

After this point, no amount of plugging or unplugging seems to change
anything: nothing appears in `dmesg`, `lsusb` shows only internal USB
hardware, and video-over-USB devices do not appear in `/sys/class/drm`.
Both USB ports are similarly unresponsive. The only remedy appears to be
to reboot.


`dmesg` shows the unplug event, but nothing after that:

[Kernel-packages] [Bug 1919307] [NEW] kernel hang

2021-03-16 Thread Richard van der Hoff
Public bug reported:

My system locked up, and stopped responding to mouse movement, keyboard,
network traffic, etc.

A few minutes later, it appeared to recover, although my X session
restarted and I had to log back in.

I found this in my kern.log:

[Kernel-packages] [Bug 1404558] Re: IPv6 related kernel panic following upgrade to 3.13.0-43

2015-02-27 Thread Richard van der Hoff
I was previously seeing this problem; I've now upgraded to 3.1.0-46 and
am seeing a similar, but slightly different, panic (see attached)

Title:
  IPv6 related kernel panic following upgrade to 3.13.0-43

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Trusty:
  Fix Released

Bug description:
  After updating a dozen machines from 3.13.0-40 to 3.13.0-43, they all
  kernel panic within the next 24 hours.

  I managed to pull the console from one over an IP KVM and it shows a panic 
related to IPv6 networking:
  https://dl.stgraber.org/panic-3.13-43.png

  All affected machines had native IPv6 connectivity to the Internet.

  Downgrading to 3.13.0-40 resolved the issue (so it's clearly a
  regression) and upgrading to lts-utopic 3.16.0-28-generic also
  appeared to do the trick.

  
  A friend also just reported seeing the exact same problem on his server which 
also has native IPv6 connectivity so the issue appears pretty widespread.
