Spurious Hard Disk Interrupts

[Charlie Pilzer]

Sometime during the last six months or so, there was a discussion
of 7300s and 3b1s suffering from 'Spurious Interrupts' from the
hard disk and/or the parallel port.  Unfortunately, I didn't
need the information at the time and didn't have the forsight
to save the messages.  I now find myself in need of this
information.  In particular, I have a 7300 with 1 MB on the
motherboard, 512K expansion Ram, 40 MB disk, & Tape that
is suffering from panics every so often (at least one a day
now).  The software is 3.0. The panics seem to occur during
periods of intense disk activity.  Initially I saw a panic
then nothing for several weeks, then another panic.  Now
the panics are happening often enough that I can cause a
malfuction at will.
