Hello,
I'm wondering if anyone might have some information relating to the
following problem.
I have the 3.0-970731-SNAP installed on a Dell PowerEdge 6100/200,
four processor machine. The problem occurs on either of the two
aic7880 onboard scsi devices, or a 2940 adapter board, when in
multi-proccessor mode. Anywhere from 5 to 60 minutes after booting
the machine, it freezes with the following messages on the console:
sd0: SCB 0x1 - timed out in command pahse, SCSISIGI == 0x86
SEQADDR = 0x8c SCSISEQ = 0x12 SSTAT0 = 0x7 SSTAT1 = 0x3
sd0: abort message in message buffer
sd0: SCB 1 - Abort Completed.
sd0: no longer in timeout
sd0: SCB 0x1 - timed our while idle, LASTPHASE == 0x1, SCSISIGI = 0x0
SEQADDR = 0xb SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0x2
sd0: Queueing an Abort SCB
It only seems to occur when I start to initiate heavy disk io. It
does not happen in the uni-proccesor situation. The complete output
from dmesg is appended to this mail. If anyone can help me track this
down, I'd really appreciate it.
Thanks,
John
