>Release:        2.6 beta (October 18 snapshot)
>Environment:
	System      : OpenBSD 2.6
	Architecture: OpenBSD.i386
	Machine     : i386
>Description:
Boot from floppy26.fs
Machine is a PIII-500mhz, 64MB ECC RAM
Soyo SY-D6IBA systemboard with integrated Adaptec 7880 SCSI
dmesg (partial):
 ahc1 at pci0 dev11 function 0 "Adaptec AIC-7880" Rev 0x01 irq5
 ahc1: Using left over BIOS settings
 ahc1: aic7880 Wide Channel, SCSI ID=7, 1 SCBs
 scsibus0 at ahc: 16 targets
 fatal page fault in supervisor mode
 trap type 6 code 0 eip e01078a8 cs 8 eflags 10286 cr2 24 cpl e0000028
 panic: trap

I also tried it with the Adaptec BIOS disabled. It reports the BIOS is
disabled and will use default SCSI device). Same page fault.

>How-To-Repeat:
Seems consistent with the boot floppy. I now own this system so I can try
things for the tester.
>Fix:
