3.2 SCSI crash

I have a i386 machine running 3.2 following stable (dmesg below). The machine was running 2.9 for over a year with no problems. I recently upgraded it to 3.2, and the machine crashed after being up for a couple of weeks.

I copied the following from the console: sd1(ahc:1:0): SCB 0x10 - timed out
ahc1: Dumping card state while idle at SEQADDR 0x7 ACCUM=0xe, SINDEX=0x64, DINDEX=0x65, ARG_2=0x2 ...

sd1(ahc:1:0): Queuing a BDR SCB
sd1(ahc:1:0): Bus Device Reset Message Sent
sd1(ahc:1:0): no longer in timeout, status = 0
sd1(ahc:1:0): target 1 using async transfers
sd1(ahc:1:0): Bus Device Reset on A:1 3 SCBs aborted

Both drives are sitting on the internal connector, and nothing is connected to the external connector.

Is this a problem with my driver, cabling, controller card, or a software problem?

Any insight is appreciated.
