HPT372 Errors even after ac4 patch

[George D. Plymale]

Just spoke with ata in #kernelnewbies several days ago and with the help of
a friend we got a kernel compiled for my box with the Iwill XP333-R in it
(as I don't have a linux dev box at the moment).  I added ata's patch to get
the HPT372 recognized as an HPT370, which seems to have done away with
garbage that was being seen at ide chipset initialization, but I am still
having the identical DMA errors as before without the patch.  The problems
start when I mkswap on the ataraid partition (or any time I ever try to
access my raid array).  The errors can be found at the tail of this dmesg
output (starting with hdg: dma_intr: status=0xff { Busy }):
