Hi all,

I have recently acquired NEXTstation and was happy to see that NetBSD
runs on it. So far I have been using NFS root mount and it worked OK.
Then I have found there are some kernel patches which enable SCSI support
on it and I waited until 1.5.1 was released. Then I have applied these
patches to new kernel. I soon run into problems, so I have downloaded
precompiled 1.5 kernel image from 

ftp://ftp.netbsd.org/pub/NetBSD/arch/next68k/scsi-20001226/netbsd.gz

I get the same errors with both kernels.

Here are some details about it :

I knwo that my disklabel output may be wrong, I am a new NetBSD user. But
would that really result in DMA issues ?
