Hi,

I've just run up -STABLE on a PIII box
with an Adaptec AIC7896 (I think) SCSI setup and
an 18G Quantum Atlas IV drive, but I see the following
after booting:
---
ahc0: <Adaptec aic7896/97 Ultra2 SCSI adapter> rev 0x00 int a irq 11 on
pci0.12.0

Its hangs around the 'Target Abort' stage but seems fine after waiting
perhaps a half-minute or so. Apologies if this is a common problem, but I
couldn't find it in the mail archives. Is this something to worry about?
Also, I'm not on the list so private replies would be appreciated.


Cheers,
Joe
