Package: kernel-source-2.4.27 Version: 2.4.27-10sarge2 Severity: important Tags: patch
kernel panic (usually during backups) on a 4-way smp machine which uses lvm snapshots. Included patch is now in 2.4.x mainline, and is as discussed on the linux-lvm list: http://www.redhat.com/archives/linux-lvm/2005-March/msg00117.html The panic has been difficult to reproduce, but the patch from the above thread does seem to fix.
