>Description:
Noticed when running the dump utility overnight, came back to system in the morning
and it was "looping" with scb timeout errors:
sd0(ahc 0:6:0):SCB0x3 - timed out while idle, LASTPHASE == 0x1,SCSISIGI == 0x0
SEQ ADDR == 0x5
sd0(ahc 0:6:0): Queueing an Abort SCB
sd0(ahc 0:6:0): SCB0x3 - timed out while idle, LAST PHASE == 0x1, SCSISIGI == 0x0
SEQ ADDR == 0x5
sd0(ahc 0:6:0): no longer in timeout
ahc0: Issued Channel A Bus Reset. 2 SCBs aborted
PR bin/4333 reported a similar problem and the suggestion was made
to upgrade to the latest 2.2-stable kernel, which I did and am
still having problems.
I tried this with any combination of the AHC options enabled in the
kernel, including none, and it occurs under every one.
The system required a hard reboot to come back on-line.
Here's my kernel probe:Oct 12 01:24:56 room101 /kernel: ahc0 <Adaptec 2940 Ultra SCSI host adapter> rev 0 int a irq 10 on pci0:10

This error occurs under heavy load. Happens every so often with the 'dump'
utility.
