	I have an Amiga 2000, with an original 2090 controller and a
Micron 2 Meg board. I seem to be experiencing frequent guru's (all 3's)
at random intervals, but normally during accesses to my disk drive.
(Seems to happen equally on reads and writes. Of course, on writes, I
have to recover the disk..)

	When I pull the 2 Meg board, I don't seem to have the problems.
Now, first, does anyone know if there are problems between the 2090 and
the Micron board? Both are probably early rev's. If anyone has heard of
a problem, is the offending piece the memory board, or the controller?

	If anyone knows a definitive solutions for this (particularly one
not involving replacing one board or the other), I will be very greatful.
