:thought there was no problem, but 1 day later, kernel logged following
:message and freeze.

I've been having precisely the same problem. One of our main boxes
crashes once every month or two with SCSI errors. This is on a DELL 2400
box with an on-board AIC7890/91 and a PCI aic7880, and quantum atlases.
I just replaced the two quantums with seagates but since the crash occurs
so infrequently I don't know whether changing the disks fixes it or
not. If not then I'll mess with the BIOS a bit.
SCB count = 200
card nextscv = 8
(da0:ahc:0:0:0):SCB 8: immediate reset. Flags = 0x4040
(da0:ahc:0:0:0):no longer in timeout, status = 34b
ahc0: issued channel A bus reset. 14 SCBs aborted.
