>Description:

Approximately 1 of 3 boots results in a "kernel trap 12 with interrupts" crash.
The crash occurs at the end of the boot process, around the message
"changing root device to wd0s1a".  After a successful boot the machine has been
crash free. I have a savecore file available. This machine was recently
upgraded from 2.2.6-R which worked flawlessly from that release date.
