Bug Description

Sometimes, when trying to shut down or suspend my laptop, it gets stuck on the console screen. If I was suspending, it eventually gives up and goes back to the X session. During a shutdown it hangs forever and the only solution seems to be to force a reboot with Magic-SysRq.

The following appears in `kern.log`:

```

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?

There is another calltrace in kern.log which might be another issue (probably need a separated bug report).

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.

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.

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.

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.]

Thanks for the update, could you bisect which commit fixes the issue since upstream 6.8 works?

Seems I was mistaken. This happens on 6.8 as well.
