Before I get ripped for posted a NRQ, I was advised that there has been
much discussion about problems with AIC-7XXX on this list and that I
should check with you since I'm running out of options and have have
received little help from the linux-kernel list...
The details are below, but I have been asked about the release and
kernel source so... The main install is SW 3.4 and the kernel was
downloaded from ftp.kernel.org before they went off the air, and it was
the full 2.0.35 sources. Additionally, this same kernel is running fine
on numerous other configurations that do NOT use the embedded AIC 7770
twin-channel SCSI.
Any and all advise and suggestions would be appreciated... I'll
subscribe to the list for the duration of this, but please copy me
directly for the next couple hours so that I don't miss anything...
Regards,
Barry

I have a brand new Intel XLCBASE8TE8FS which comes with zip except a
chassis, power supply and motherboard but on the MB is an embedded
AIC7XXX dual-channel chipset. I've added the processor, IDE drives,
SCSI CD, RAM, and a diskette and everytime I try an initial boot off the
SW
installation set using SCSINET.S, it reports seeing the seeing the
aic7xxx chip set, enables the channels even though I'm only using
channel A, resets the bus, and then moments later I see :
aic7xxx: (aix7xxx_isr) Encountered spurious interrupt.
scsi0: BRKADRINT error (0x1):
Illegal Host Access
Kernel Panic: scsi0: BRKADRINT, error 0c1, seqaddr 0x0
and the system halts. I've tried swapping out the CD with another and a
hard drive, because ultimately I want them on-line too, but regardless
of the SCSI device, I get the same exact error. I don't think channel B
has anything to do with it, and to confirm that I tried terminating the
bus and then I disabled the channel in BIOS, neither attempts altered
the results, still a panic.
This does not appear to be a new issue as I have seen posting for both
SW and Debian from others experiencing the same error with similar
configurations, but none of the postings has any accompanying
resolution.
Suggestions?
Barry
