Hello,
	I am trying to install Debian Linux with the 2.0.0 kernel. I am getting
the following error.

aic7xxx: Resetting the SCSI bus...done
NCR53c4060: no available ports found
aic7xxx: (aic7xxx-isr) Encountered spurious interrupt.
aic7xxx: (aic7xxx-isr) BRKADRINT error(0x1):
	Illegal Host Access
Kernel panic: aic7xxx: (aic7xxx-isr) BRKADRINT, error(0x1) seqaddr(0x0)

I am running on a HP Netserver 5/66 LF.

CPU: Pentium 66mhz
Memory: 32meg
SCSI is an integrated AIC-7770

I have used the "aic7xxx=extended,noreset" parameter at the boot: prompt
with both "extended" and "noreset", only "extended", only "noreset" and
with out the parameters and I always get the same error.

As far as I can tell from the documentation this should be a supported
configuration.

Any help would be appreciated. If you respond would you please CC my
address on the note I am not sure if my subscription to the list took.

There was a major patch to the aic7xxx driver that was originally
applied to kernel 2.0.7.  The patch became part of the regular kernel
2.0.13.  I was having similar problems upgrading to the 2.0.0 kernel
until I sent mail to the aic7xxx maintainer and got pointed to the
patch.  He (Dan Eischen) said that the patch had fixed many bugs.

In order to do a complete install, you'll need a kernel that includes
this patch on your installation boot disk.  If you (or a kind
acquaintance) builds such a kernel, they need to have it support ramdisk,
and to use the rdev.sh script on it (also on the boot disk).  The
installation boot disk is in DOS format, so you can copy to/from it
with mcopy.  Also, the debian installation procedure will complain
that the modules directory is empty (on the boot disk), but this isn't
serious (if you aren't using modules).

Here's where I got the patch and 2.0.7 sources.  You might also just
get a regular kernel later than 2.0.13 and skip the patches:

Good luck, and write if you need clarification.
