Hi,
I'm seeing a similar problem on my system with frequent soft lockup
messages and machine check events logged.
Distributor ID: Ubuntu
Description: Ubuntu 8.10
Release: 8.10
Codename: intrepid
Errors with linux-image-2.6.27-11-server (64-bit). It's not clear if
there are specific activities triggering the bug. Rolling back to Hardy
kernel (linux-image-2.6.24-23-server) seems to have addressed the
problem - no error messages in last 12 hours of heavy system activity.
System has 2 x Western Digital WDC WD10EADS-00L5B1 drives (1TB) in RAID1
config (for both root partition and swap partition).
