Boot failure on 4000/500A

[George Harvey]

Hi,

Having succeeded in getting OpenBSD running on my 3100/95, I thought I'd
give it a try on my 4000/500A. The installation process ran through
smoothly but the kernel fails to find the root filesystem and panics
when booting from local disk:

booted from device: ra1
root on ra1a
rootdev=0x910 rrootdev=0x910 rawdev=0x912
filesystem type 0 not known.. assuming ffs
panic: cannot mount root

I've included the full console output and stack trace below. I've also
tried a recent 4.1 snapshot and that fails in a similar way.

Some additional info: The SCSI controller is a CQD-223/TM with two 2G
drives attached, OpenBSD is on the 2nd drive. I have also checked that
there really is is a root filesystem on the disk by mounting it on
another system.

Thanks,
George
