Bug#516635: linux-image-2.6.26-1-xen-686 kernel panic: Fatal exception in interrupt / iret exception
Package: linux-image-2.6.26-1-xen-686
Version: 2.6.26-13
Severity: importang
Our Xen host experienced multiple crashed so we set up a remote system
logger to get the call trace. The Xen hypervisor doesn't seem to log
anything, though it might just be disabled.

Feb 22 20:05:08 hummer [253575.999113] Kernel panic - not syncing: Fatal
exception in interrupt
Previously, we also experienced some problems when polling SMART data
from the hard drives, causing the dom0 to slow down any I/O which
resulted in very high loads (>30 sometimes). After flashing the RAID
controller, these problems seemed to be gone, though now this kernel
panic happend. Not if the SMART problem is related, just mentioning
here.
Debian bug #504805 looks somehow similiar to our kernel crash, though
the call stack slightly differs from this one.
Unfortunately, I can't give any reliable information on the hardware, as
the machine is down at the moment. As far as I remember, it is an old
compaq server with 4x Intel Pentium III. I'll hand in more precise
information as soon as the machine is back online.
