Oddly enough, what I did in the Cyclades driver was to add a call to
the interrupt handler every time it made a trip through the
"top half" polling loop.

It didn't fix the interrupts, but it got the job done.

Well, it kept calling the interrupt handler so even if the signalling mechanism was borked the interrupts were dealt with eventually.

On the 4.0.1 machine,
I can set up an account on the machine for debugging,
or run some tests, w/ extra debug code on the machine in
question if that is helpful.  I would need a patch or at least
some pointers on what debug code would be required.  It's a
production machine, but I can "mess with it" at will because all
it does is monitor the other machines, so its operation is
not critical.

First you should try to reproduce the problem and maybe narrow it down a bit. I have a beige G3 here but I'd have to get a serial cable somehow, my mini-DIN->DB9 adaptor seems to have wandered off.

have fun
Michael
