I got the following panic on 9-current, r216869, amd64 SMP on a core 2
duo system. I'm running the older version (from 2011-01-01) to try and
determine where the problem I'm having with stability on -current first
occurred. If this problem was fixed between now and then, no worries.
This panic happened during heavy disk activity on the ext2fs partition.
The file core.txt.0.216869 is in my home directory on freefall if anyone
wants to take a look.
