I noticed the posting at:

and was curious if a solution had been found for this
problem (kernel: ad4: FAILURE - READ_DMA
status=51<READ, DSC, ERROR> error=84<ICRC, ABORTED>).

I have the same problem with a PCI promise Ultra100
TX2 controller card and 200GB Western Digital 2000JB
drive on startup.

I've double-checked that the cable, controller, and
drive are all working by plugging them by accessing
them through DOS and Windows 2000; the drive shows up
just fine and produces flawless I/O.  My drive is
jumpered as single/master, set to ATA100, and the
cable works just fine.

I've noticed other postings with a similar error, but
the only suggestion given was either controller
failure or cable failure.  In my case I'm certain that
neither is the cause of the problem.

Any ideas?
