i don't think that it has something todo with 2100 or 3100 - it is
more a point of the disks you use - but i haven't found any real point
here

i just can see that i also noticed that on 2 2100's - as long as i
used the second disks too it hangs on heavy disk access:

rz0 at sii0 drive 0 slave 0 SEAGATE ST1480 rev 7336, 832527 512 ...
rz2 at sii0 drive 2 slave 0 FUJITSU M2614S rev 0606, 356178 512 ...

and

rz0 at sii0 drive 0 slave 0 FUJITSU M2624S-512 rev 0202, 1015812 ...
rz3 at sii0 drive 3 slave 0 SEAGATE ST1480 rev 5830, 832527 512 ...

now i only use the rz0 disks on both machines and they are working
fine - i compiled a lot of stuff on them without any problems - they
are up more than 30 days now

also some people which were trying to install another BSD on a pmax
(it is from the pamx specific code nearly identical to NetBSD/pmax -
especially the scsi code is identical - so all all results coming from
them arealso valid for NetBSD/pmax i think - so i hope that it is ok
to tell it here too) told me about problems with various disks - one i
think had problems with HP97548 disks (he tried 3 of them without
any success and got it working with a toshiba disk i think - i can
look it up exactly in my mail at home) and one did'nt get it working on
a seagate 31200 i think - but it worked fine on a jaz drive ... don't
know about the hp disks - but for me it looks like there are problems
with newer disks - i haven't heard anything about problems using dec
rz disks (but i think someone in this thread also had problems with an
rz25 :-( )

at all my result from all this that it is really worth trying various
disks - some of them may work - this is no solution - but maybe it
helps to get maybe some of the 2/3100 mentioned here up if you have
access to other disks to try - maybe

good luck
