Things are getting worse.  When I boot, fsck fails and running it
manually it succeds on my first ide drive (the one with / on it) but
then while checking my SCSI drive it dies from a sig 8:

--- manual fsck run ---
*** /dev/rsd0s1e
BAD SUPERBLOCK: VALUES IN SUPERBLOCK DISAGREE WITH THOSE IN FIRST ALTERNATE
pid 13: fsck: uid 0: exited on signal 8
floating exception
--- manual fsck run ---

I tried it several times and it always dies the same way.

I don't have any spare ones.  I'd just have to remove one bank at a
time.  But are sig 8's indicative of bad SIMMs?

I *need* this to be a software problem, I can spare the time to
reformat/reintsall/whatever, new hardware is a different story...


Thanks,
