We have 4/280 that prints that message out every 10-15 minutes or so, but
it doesn't crash.  I always thought it had something to do with having a
second ethernet interface, since it's usually followed by the the famous
"ie1: spurious interrupt" message.  We have a Xylogics 451, a SCSI 1/4"
tape, a 32 meg memory card, an ALM-2 and a TAAC board.  Field service gave
the generic "it's fixed in the next rev" line, but I've heard it could be
caused by the VME to Multibus adapter cards used by ie1 and the 451.  The
rate of the error messages does seem to increase when the network
interface is used, such as during a remote dump.  We also tried upgrading
to the newest rev cpu (rev 14?) with no change.  I would assume they would
pay more attention to you if it actually crashed your system, instead of
just wasting console paper.
