I have the same problem - I have an Asus A7N8X using the SiI3112A, with a
Seagate Barracuda SATA ST380023AS. It comes up (and works, but very slowly)
in pio.

When I enable DMA with hdparm -d1 /dev/hde, or hdparm -Xudma2 -d1,
then I get the dma_timer_expiry messages above, and then a hard lock.

When I enable DMA with hdparm -Xudma6 -d1, or hdparm -Xudma5 -d1, then the
DMA enables, I can hdparm -t to see that transfer rate is much better (25x)
than before, but as soon as I write to the drive I get the dma_timer_expiry
messages above. 

(Dual-boot Windows XP is using UDMA6 for this drive)

There's similar behaviour under 2.4.20, 2.4.21rc5ac2 and 2.4.21rc6.

The console messages after enabling DMA (these are copied down from my 
digital camera, so may not be exact, but I think they're pretty close)

hde: dma_timer_expiry: dma_status == 0x21

hde: status timeout: status=0xd8 { Busy }
ide2: reset phy, status=0x00000113,siimage_reset

end_request: I/O error, dev 21:01 (hde), sector (something)
end_request: I/O error, dev 21:01 (hde), sector (something)
journal-601, buffer write failed
kernel BUG at prints.c:334!
invalid operand: 0000
(and then some stack information and call trace information - if this 
is useful, I can type it in too, but it looks essentially like reiserfs
complaining that the disk isn't working)
