Bug#359266: linux-image-2.6.15-1-686: generates "Bad page state" at miscellaneous processes, & sometime crashes
Package: linux-image-2.6.15-1-686
Version: 2.6.15-8
Severity: normal
*** Please type your report below this line ***
Occasionally the kernel broadcasts a message such as:
Message from syslogd@localhost at Mon Mar 27 14:19:59 2006 ...
localhost kernel: Bad page state at free_hot_cold_page (in process 'XFree86', pa
ge c13ff320)
Message from syslogd@localhost at Mon Mar 27 14:19:59 2006 ...
localhost kernel: flags:0x80000000 mapping:00100000 mapcount:0 count:0
Message from syslogd@localhost at Mon Mar 27 14:19:59 2006 ...
localhost kernel: Backtrace:
Message from syslogd@localhost at Mon Mar 27 14:19:59 2006 ...
localhost kernel: Trying to fix it up, but a reboot is needed
Similar messages refer to different processes, not just XFree86, so this
seems a true kernel problem.
See the 3 following examples, extracted from recent /var/log/syslog.* :

Mar 27 14:19:59 localhost kernel: Trying to fix it up, but a reboot is needed
On the first occurrences I did reboot, but now I just ignore these
messages: if I wanted to reboot every couple of days, I'd run on windoze,
not linux...
I would not mind these messages, except that the system is now unstable and
experiences occasional crashes.
The system was perfectly stable with 2.6.8.
I experienced similar problems with 2.6.12, and hoped they would be fixed
on 2.6.15. Now, due to damn bug #349354 it is not clear how to go back.
I'd also prefer 2.6.15, which makes my sound card work better.
I've seen similar reports, e.g. #353700, but attributed to different
packages. But I suspect we actually have a kernel problem here.
For further reference, my system is a
vendor_id : GenuineIntel
cpu family : 15
model : 4
model name : Intel(R) Pentium(R) 4 CPU 3.00GHz
stepping : 1
cpu MHz : 2995.056
single processor with 1GB ram.
I can provide more details upon request.
Thank you,
Nick
