Bug Report Logs (kern.log, lsmod, lspci, debconf)

After a semi-random period of normal operation (anywhere from a few hours to a week) the machine will suddenly get a series of page allocation errors followed by a series of "soft lockup - CPU#[X] stuck" messages after which the machine is completely non responsive and has to be hard restarted.

I've seen this occur on two other systems in addition to this one.

I have already filed this with the Debian project (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=548397) and they suggested I file it upstream.

Thanks,
