Package: linux-image-2.6.26-2-686-bigmem
Version: 2.6.26-19lenny2
Severity: normal
One of our i386 KVM VMs has been crashing every couple of days, with the
following oops output.
linux-image-2.6.30-2-686-bigmem=2.6.30-8 (from squeeze) made no difference,
but linux-image-2.6.32-trunk-686-bigmem=2.6.32-5 from unstable has gone
without a crash for over a week now.
