I tried the 11/29 snapshot, it is indeed worse.  I got a failure during the 
install's fsck.

The errors I got were:
ad4: Warning - WRITE_DMA recovered from missing interrupt
ad4: Failure - WRITE_DMA status=ff<I couldn't copy the codes here, sorry>

followed by lots of:
ad4: timeout sending command=ca
ad4: error issuing DMA command

All along I have experienced "missing interrupt" errors, along with DMA 
write errors.
