Not only newfs. Tar has paniced the system also while extracting the
base.tgz (...gzip is used..).
Do you mean that the DMA Buffer from the NCR driver overlaps an Area that
mmap has given to newfs?


I have now the -current from David running on the M28, no not right, but
the install system. I've mounted some directory from my FreeBSD WS and the
M38 is extracting flawlessly the binary sets over nfs.
It isn't a direct comparsion, but last time I've tried this on the M76 on
to the disk tar paniced the system.
The M38 hs 24MB RAM the M76 only 16MB but the errors are similar
(disklabel, newfs, tar). All have todo with disk activity.
So in my opinion the cpu (Rigel or CVAX) is irrelevant here.

I've found a posting from 2002 on the Net:

http://osdir.com/ml/os.netbsd.ports.vax/2002-10/msg00053.html

I would try this. Does someone know where I can get an 1.5.2 iso image
for vax from?
