:hw.ata.wc=0
:hw.ata.ata_dma=0
:hw.ata.atapi_dma=0

It's worth updating to the latest -stable kernel. At least one other
person has reported filesystem corruption due to kstack underflows which
went away when I bumped UPAGES from 2 to 3. I don't think the stack
fixes for the IDE drivers have been MFCd to -stable yet so heavy IDE use
could be hitting up against the kstack problem.
