Hm, that's bad. It might be caused by the scsi changes in -mm. I assume that 2.6.12-rc6 does not exhibit this bug? I'm about to disappear for 3-4 days - please remind me to look at this if it seems that I've forgotten ;) If you can do a bisection search through the patches in -mm that would help. I'd amek the first pivot point be around git-scsi-misc.patch.
If you disable preempt, does that help? And this doesn't occur on 2.6.13-rc6, right?
I looked for 2.6.13-rc6 and this panic doesn't occur for this. But for 2.6.13-rc5-mm1 I tried to build with CONFIG_PREEMPT disabled still it gets into panic. I will attach the Console output with preempt disabled

Is this still an issue with latest -mm tree ? Otherwise, can we close it ?
Its not observed in the latest kernel 2.6.14-rc2-mm1 and 2.6.14-rc2-mm2 kernels
Closing bug since you no longer can reproduce.
