panic: ahc0 (AIC-7770)

["Adam N. Thompson, MCNE, MCSE" <athompso@commerced.com>]

OK, I was setting up an older machine to try and test out Tobias'
changes to the ahc* code but I didn't get very far.

I grabbed the i386 snapshot (as of ~8pm CST, 2000-Feb-05), wrote
"floppy26.fs" to a floppy and booted... and I got this:

	ahc0 at isa0 port 0x1c00/256 irq 11: Adaptec AHA-284x SCSI (BIOS
enabled)
	ahc0: aic7770 <= Rev C, Single Channel, SCSI Id=7, 4 SCBs
	scsibus0 at ahc0: 8 targets
	panic: ahc0: brkadrint, Illegal Host Access at seqaddr = 0xd

I have absolutely no idea what that error message means, but it does
prevent me from proceeding... :-(

The system is a VL-bus board (GigaByte GA-486VS) with an AMD486DX4/100
CPU.

Hardware present includes: 
	(VLB) ATI Gr. Ultra Pro OEM 4Mb (mach32)
	(VLB) Adaptec AHA-2842 (aic7770)
	(VLB) Boca Super-I/O (VLIO-2?)
	(ISA) Microsoft Sound System (the original!)
	(ISA) WD8013EWC
	3.25" Floppy, plugged into AHA-2842
	SCSI CDROM (Toshiba) - ID #5, plugged into AHA-2842

	Pri. IDE on Boca enabled, no devices connected
	Sec. IDE on Boca disabled, no devices connected
	Floppy on Boca disabled, no device connected
	Floppy on AHA2842 enabled & connected

Any advice would be appreciated.
