Hi

After a while (3 mins from boot to a day or so) I start getting
the following messages on my console:
(this sequence repeats infinitely so I'm not sure if the SCSI
problem causes the pager problem or the other way around)

My kernel config has the follwing relevant lines:

options         AHC_TAGENABLE
options         AHC_SCBPAGING_ENABLE
controller      ahc0
controller      scbus0  at ahc0
device		cd0
device		sd0
device		st0

I have a Gigabyte 686DLX motherboard with one PII-266.

Does anyone have any ideas?
