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)

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.* :

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
