Install of OpenBSD on DEC 5000/200 fails

[Jan Fischer <Jan.Fischer@e-technik.tu-chemnitz.de>]

Hello!

I have a problem whith install OpenBSD on a DECstatin 5000/200. The 
machine has no graphic-adaptor and I'm working with a VT420 over
the serial-interface number 3. The machine has two harddisks from
DEC whith about 300 MByte and 600 MByte and a SCSI-CDROM from
NEC.

If I install OpenBSD on the machine I get the message

asc_intr: ignoring strange interrupt tc 5603 fifo residue 1

                                        ^^^^
This number has 4 digits but the value is different.

If I get this message, gzip and/or tar fails. After a little
time I get the core dump.

mode = 040755, inum = 12288, fs = /mnt
panic: ffs_valloc: dup alloc
syncing disks... done

dumping to dev 1511, offset 32768
dump succeeded
rebooting

NetBSD make no trouble at the machine.

Sometime I get a message from SCSI-interface, that one of the two
DEC-harddisks have a problem. I don't know, if this is the same
problem or a other problem. Can it be, that both SCSI-DEC-hard-
disks are out of order?

Thanks for help
