Well, what an exciting weekend we had! Three lockups/panics: two
during running a dump (mksnap_ffs seems to be the culprit) and one
running background fsck after rebooting from the prior crash.
Details are posted at http://vivek.khera.org/scratch/crashlogs/
I have the crashdumps available to a kernel hacker upon request (i'd
rather not make them generally available to the public...)
