Apparently a recent regression.

It's on sparc32 (and SMP on top of that, scary) which is only lightly
maintained, so it could be anything. It would be interesting if
running a uniprocessor kernel made the problem go away.
I would only be concerned at the scsi layer level if you see a sparc64
report like this.
