Description Timo Lindfors 2005-08-18 00:15:38 UTC
Distribution:
Bug happens with both Debian GNU/Linux 3.0 and 3.1
Hardware Environment:
Bug happens both with an old Compaq deskpro with intel pentium at 200MHz and
another computer with "AMD-K6tm w/ multimedia extensions" that has "0000:00:01.2
USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB (rev 01)"

Problem Description:
Linux stops responding completely if I unplug my "Pencam" usb webcam when it is
capturing frames. System does not respond to ping but fortunately sysrq and
netconsole still work. This bug seems to happen with 2.6.12.4, 2.6.10 and 2.6.7.
It does not happen with 2.4.31.

Steps to reproduce:
1. cat /dev/video0 > /dev/null &
2. unplug webcam

*** Bug 4372 has been marked as a duplicate of this bug. ***
Comment 3 Greg Kroah-Hartman 2006-02-14 16:45:56 UTC
Does this still happen on 2.6.16-rc3?
Comment 4 Timo Lindfors 2006-02-15 05:20:57 UTC
Yes, unfortunately the bug seems to be present in 2.6.16-rc3. However, this time
unplugging the webcam seems to also produce some kernel messages before the
system freezes:

Losing too many ticks!
TSC cannot be used as a timesource.
Possible reasons for this are:
  You're running with Speedstep,
  You don't have DMA enabled for your hard disk (see hdparm),
  Incorrect TSC synchronization on an SMP system (see dmesg).
Falling back to a sane timesource now.

Probably the stv680 driver is caught in a tight loop, submitting URBs that fail
almost immediately, and not leaving time for khubd to call its disconnect routine.
Comment 8 Natalie Protasevich 2007-06-12 12:10:11 UTC
There were several fixes that I believe went into 2.6.22-rc4 and were taking care of proper shutdown/unregister of usb-serial devices. 
Would you like to test this kernel with your webcam?

Thanks,

Comment 12 Timo Lindfors 2007-08-29 01:06:22 UTC
I managed to finally test this with 2.6.22. First unplug seemed to work and printed only

[ 1067.295444] usb 1-2: USB disconnect, address 2
[ 1067.300458] drivers/media/video/stv680.c: [stv680_video_irq:669] STV(e): urb burned down in video irq

However, when I started cat /dev/video0 & again and unplugged the camera for the second time I hit the bug again:

[ 1118.159639] drivers/media/video/stv680.c: [stv680_video_irq:669] STV(e): urb burned down in video irq
[ 1118.160958] usb 1-2: USB disconnect, address 3
[ 1118.180676] BUG: unable to handle kernel NULL pointer dereference at virtual address 00000004
...

I continued to replug and unplug the camera for a while but did not manage to freeze the system completely this time. See attached config, dmesg and netconsole output and don't hesitate to ask for more info.
Comment 13 Alan Stern 2007-08-29 08:02:07 UTC
This looks like a pretty elementary error in the stv680 driver: there's no reference counter to protect the device structure from being deallocated while it is still in use.

You should complain to the author/maintainer of the driver: Kevin Sisson <kjsisson@bellsouth.net>.
Comment 14 Timo Lindfors 2007-08-29 10:29:11 UTC
Hmm, there seems to be this stv680->user flag though? But do you mean that in stv680_template .release video_device_release which will do kfree() without checking if the device structure is in use? I'm total newbie on linux internals so I also mailed Kevin Sisso link to this bug report in case he has time to take a look.
Comment 15 Alan Stern 2007-08-29 12:16:36 UTC
Yes, that's what I meant.  I don't know anything about the V4L internals, but having stv680_disconnect() call video_unregister_device() doesn't seem like a good idea, given that there's no way to tell the video core that the device is still in use.
Comment 16 Natalie Protasevich 2007-09-23 10:27:17 UTC
Adding Mauro to assess the driver problem, maybe needs to be passed on to Kevin Sisson? (he's not subscribed to bugzilla).
Thanks.

This should now be resolved.
