Description Bernhard Auzinger 2004-09-20 02:16:47 UTC 
Almost everytime when I'm using xawtv, my kernel crashes after a period of time. There is no way to restart the system with MagiqSysRq. This problem occurs only with xawtv. Other TV programs (f.ex. tv-time) work very well. This problem occurs with version 3.86-r2. I've also tried xawtv-3.94 (marked  with keywords) having the same problem with the bttv-driver.

Syslog has reported the following lines:

Comment 1 Doug Goldstein (RETIRED) gentoo-dev 2004-09-20 21:38:03 UTC 
This isn't a mobile thing. Your kernel isn't properly handling prempt's
Comment 2 Bernhard Auzinger 2004-09-20 23:12:55 UTC 
I saw it, but why? What should I do with the bug report?
Comment 3 Bernhard Auzinger 2004-09-26 04:36:13 UTC 
My Problem has nothing to do with PREEMTS. Look what I got with PREEMTS disabled. I thinkt there is ab bug in the kernel. Look at the following line of my kern.log:

Sep 26 13:10:14 nordpolcamper kernel: kernel BUG at include/linux/list.h:165!

My kern.log: http://stud3.tuwien.ac.at/~e0026053/kernel.log

If you can still reproduce this with 2.6.9-rc2 then you should file a bug at http://bugzilla.kernel.org - this appears to be an upstream issue.
Comment 5 Daniel Drake (RETIRED) gentoo-dev 2004-09-26 05:39:52 UTC 
...and you should also mention this to the xawtv authors
