I haven't tried the rsync'd tree yet, my machine was crashing in the same
SCSI initialization. I have an on-board ncr53c8xx fast-wide chip, so this
leads me to believe there is some interaction between the memory
management code and the SCSI init code.

Is this something we should bring up on the regular linux-kernel list?
Maybe someone there would have an idea what is broken.

I don't know if this is related, but I also get crashes when doing nfs
access (checking out files from my local CVS archive, in particular).
I traced it one time and it appears a pointer is getting trashed in
