Comment 1 Arjan van de Ven 2004-09-09 09:46:56 UTC
are you using any kind of external kernel modules?
or any "less common" applications ?

Comment 2 Pawel Orzechowski 2004-09-09 09:59:21 UTC
Created attachment 103630 [details]
gziped /var/log/messages file with the error

The attached file is a syslog file from a few days (with some restarts of the
machine), showing how the error has occured.

Comment 3 Pawel Orzechowski 2004-09-09 10:05:19 UTC
There is no external modules or any "less common" applications I can 
think of (maybe rdesktop). I will attach lsmod and ps -fe output. 

Comment 4 Pawel Orzechowski 2004-09-09 10:06:14 UTC

Output from lsmod command

Comment 5 Pawel Orzechowski 2004-09-09 10:07:46 UTC
Created attachment 103632 [details]
Output from "ps -fe" command

Comment 6 Dave Jones 2004-11-27 21:53:12 UTC
Is this still a problem with the 2.6.9 based kernel update ?


Comment 7 Pawel Orzechowski 2004-11-29 22:05:08 UTC
No, there is no problem any more. 

Comment 8 Pawel Orzechowski 2005-01-27 18:27:30 UTC
Because the problem does not seem to occur anymore with current 
kernel releases, I'm closing this bug report as resolved.
