Description Vladimir Kondratiev 2006-04-20 10:53:07 UTC

Most recent kernel where this bug did not occur:
Distribution: Fedora Core 5
Hardware Environment: IBM T42p, Plantronics 400 USB headset
Software Environment:
vanilla 2.6.16 kernel
ALSA sound
ask for other details that may be relevant, I don't want to list here whole .config

Problem Description:
When I remove USB headset while audio device is in use; kernel oops occurs when
last process that uses this audio device, terminated. System continue to
function, but process mentioned usually can't be killed. This means, suspend
will not work.

Steps to reproduce:

- plug USB headset.
- run some program that use it. 'alsamixer -c 2' is just fine.
- unplug USB headset
- quit alsamixer
- observe oops in /var/log/messages.

Comment 1 Greg Kroah-Hartman 2006-04-20 13:43:20 UTC

I don't see any USB or sound specific function in this callback at all.

Does this happen on 2.6.17-rc2 also?

Comment 2 Vladimir Kondratiev 2006-04-22 13:48:52 UTC

will try 2.6.17-rc2 tomorrow. there is rc2-git4 as well. which one it better to
start with?

Comment 3 Greg Kroah-Hartman 2006-04-22 15:12:13 UTC

Either is fine, the -git one is newer, so would be nicer to have you test,
if you can.

Comment 4 Vladimir Kondratiev 2006-04-23 11:18:27 UTC

I checked with 2.6.17-rc2-git4; oops is reproducible.

Scenario:

- boot fresh compiled 2.6.17-rc2-git4
[vkondra-l@vkondra-mobl ~]$ cat /proc/version
Linux version 2.6.17-rc2-git4 (root@vkondra-mobl) (gcc version 4.1.0 20060304
(Red Hat 4.1.0-3)) #1 PREEMPT Sun Apr 23 09:52:24 IDT 2006

- plug usb headset.

- run 'alsamixer -c 2' (it is for headset)

- unplug headset. the following oops printed to /var/log/messages

Comment 5 Vladimir Kondratiev 2006-05-13 10:25:16 UTC

I re-checked with 2.6.17-rc4. Same scenario: plug headset; run "alsamixer -c 2";
unplug headset.

Comment 6 Greg Kroah-Hartman 2006-08-30 00:44:32 UTC

Ok, this is an alsa issue, reassigning...

Comment 7 Natalie Protasevich 2007-06-13 11:53:37 UTC

Vladimir, any updates on the problem? have you tried newer kernels since then?
I am going to cc to asla-devel...

--Natalie

Comment 8 Vladimir Kondratiev 2007-07-08 00:10:29 UTC

Checked 2.6.21.5. No problem with USB audio removal while in use. I run mplayer with audio directed to USB, then removed USB plug. mplayer hangs of course, but nothing bad happens with the system.
Close?

Comment 9 Natalie Protasevich 2007-07-08 00:43:37 UTC

Great, thanks. Can be closed now.

Comment 10 Natalie Protasevich 2007-07-08 00:47:01 UTC

(On the other hand, maybe try 2.6.22+? There were updates for USB device removal/shutdown, maybe you can give it a shot?)
