Hi,
with 2.6.20-rc{2,4,5} (no other tested yet) I see SATA exceptions quite
often, with 2.6.19 there are no such exceptions. dmesg and lspci -v
output follows. In the meantime, I'll start bisecting.
...

Looks like all of these errors are from a FLUSH CACHE command and the
drive is indicating that it is no longer busy, so presumably done.
That's not a DMA-mapped command, so it wouldn't go through the ADMA
machinery and I wouldn't have expected this to be handled any
differently from before. Curious..
