Xen 4 rc2, with linux pvops dom0 and a kernel.org domU (2.6.32.7), all
64-bit.
I don't know if it's a bug in the domU kernel, dom0, Xen, or a hardware
problem.
I did a full e2fsck on this partition a few days ago, and I ran a full
Western Digital diagnostic on the HD (no problems), so the ext3
corruption must have come in recently. I did another WD diag test after
the crash, again no problems.
I've been getting random segfaults on this domU ever since upgrading to
Xen 4 on a new motherboard (unfortunately I can't use the 2.6.18
linux-xen dom0 because it doesn't have the drivers to boot on this
motherboard).
Yesterday I stress tested the CPU by doing a full kernel rebuild on all
4 cores (rebuilding in an infinite loop). I don't know if this is a good
test, but there were no errors after 50 rebuilds. I've also done a full
memtest86 at least 4 times, with no errors.
Console and e2fsck dump below.
Thanks,
Yasir
