Hmmm...  Just a thing I was having troyuble with ...  Are you saying that you can now use DMA, not PIO mode with it?  I tried your patch, but I still have the same problem with BP6/HPT366:

[dmesg output]
Nov  3 19:07:53 vogon /boot/kernel/kernel: ata2: at 0xd000 on atapci1
Nov  3 19:07:54 vogon /boot/kernel/kernel: ad4: 19623MB <IBM-DTLA-307020> [39870
/16/63] at ata2-master UDMA66
...
Nov  3 19:07:54 vogon /boot/kernel/kernel: ad4: READ command timeout tag=0 serv=
0 - resetting
Nov  3 19:07:54 vogon /boot/kernel/kernel: ata2: resetting devices .. done


However, if I have something like:

hw.ata.ata_dma=0

in /boot/loader.conf everything is fine (except that harddrive is used in PIO mode instead of DMA).

Maybe it's my IBM drive that is fooling around?...
