Sun Xylogics disk controller Reset Retry error

[Brian Kantor]

We recently have gotten several of these
	xy0: reset retry
(or something like that) error messages.  I've been unable to trace them
down to anything specific, like loose cables or a specific program
running.  They are occuring on a Sun-170 disk server (no graphics), with
two megs main memory, two ethernet (3-com) boards, and an Eagle.  The
controller has prom set 'C'.  We are serving 5 to 6 diskless clients.

Any ideas?  These are real annoying, since they usually wind up eating
the super-block in the root partition, crashing the system, and then I
have to reboot from tape into the swap area in order to run fsck to
repair the munged superblock.  Its a real pain.  (Sun doesn't have a
standalone fsck as far as I know, which would really help too!)

Please MAIL your answer to me.  I'll summarize to the net if interest 
deserves.
