3Ware maintains a list of motherboards where 32bit support works. It will
only run 64bit on many board (most of the Intel server boards for example).

You may want to check that list for your board(s) (I was too lazy to look it

Also, I've seen some of the 7500's still shipping w/ old firmware.

And, like a lot of PCI problems, it could be the slot. If you can, move it
to a different slot. I've also seen this problem on riser cards that share
the same pci slot with other cards. Some of the newer risers have little
daughter-boards that plug into adjacent slots to rememdy that problem.

Good luck,
