I'm getting this error during heavy disk activity:

ad0: READ command timeout 
tag=0 serv=0 - resetting
ata0: resetting devices .. done

This happens with READ and WRITE from time to time.  Recently I saw:

Falling back to PIO mode
and 
Waiting for DRQ	(IIRC)

This sounds ominous.  Is my drive on its last leg?
