[ Hmm... The subject line caught my attention since FM was the name of
a project I worked on some years ago.  It stood for "F***ing Magic".
I think you actually meant "FW ERRORS"! ]

[ I notice that several people are having similar problems, thus my
posting. ]

Yup, a dead machine certainly has poor performance!

This means your disk is either un-formatted, or bad.  Literally the
sanity track on the disk cannot be read, or is garbage.

You can try re-formatting the disk.  To do this you need either
devtools or idtools, which normally come with the "3b2 Maintenance
Manual".  You can get one of those by calling (in the US only)
1-800-828-UNIX, and putting ~$60.00 tab on your credit card (though
you might want to look up the select code in the documentation
catalogue first).  There is also a companion manual listing *all* of
the potential error messages, both from firmware, and from the kernel,
with explanations.  A third manual completes the set, but I can't
recall just what it's all about (they are at home).  Anyone who can't
afford AT&T maintenance really should have this set of manuals.  There
is a fourth manual available to AT&T internal customers only, called
the "3b2 Technical Reference".  I wish I could buy a copy of that one
too!

You also might find a friend nearby with a copy of idtools you could
borrow to work on your disk..

Another way of saying this is "Unexpected Interrupt".  Either your
system board is dead or dying, or some peripheral is.  You need
hardware service on this one.
