Has anyone seen this problem:
On an Amiga A2000 with a V4.2 motherboard (only V4.2 exhibits this problem),
if a 2 Meg expansion board is used in the system along with a 2090A auto-boot
controller and a hard drive with a FFS partition, everthing works just fine
(in this case the 2 Meg board is ASDG 2 Meg board).  Now remove the 2 Meg
board and replace it with an 8 Meg board populated with any amount of memory
(2, 4, 6, or 8 Megs) and you can no longer use a FFS without crashing the
machine whenever a file is loaded from the FFS partition.  I have verified
this on two different A2000 V4.2 motherboards using 2 different ProRAM2000
memory boards and 1 8UP-DIP memory board.  Commodore claims that there is not
a problem with the 4.2 motherboards.  All three of these memory boards work 
just find on other versions of the motherboard.  So does the 2090A controller.

If anyone has a V4.2 motherboard and is using a hard drive with FFS using any
other controllers and an 8 Meg memory board and everything works fine, please
let me know your configuration so we can resolve our problem.

If Dave Haynie is listening, please help me solve this problem.
