Ever since I upgraded to 3.1-RELEASE, I've occasionally been seeing bursts like this: Mar 21 20:01:22 caern /kernel: (da0:ahc0:0:0:0): SCB 0x18 - timed out while idle, LASTPHASE == 0x1, SEQADDR == 0x9 Mar 21 20:01:22 caern /kernel: (da0:ahc0:0:0:0): Queuing a BDR SCB Mar 21 20:01:22 caern /kernel: (da0:ahc0:0:0:0): Bus Device Reset Message Sent Mar 21 20:01:22 caern /kernel: (da0:ahc0:0:0:0): no longer in timeout, status = 353 Mar 21 20:01:22 caern /kernel: Unexpected busfree.

Mostly, it happens while the system is idle and when I get back, everything is OK. This last time, the disk system was frozen and I had to Hit The Big Black Button. Things rebooted normally. Ordinarily I'd say the drive is wonky, but my suspicions are aroused: things ran fine under 2.2.6, and this bad stuff started happening as soon as I installed 3.1. Any takers?
