This is a known bug that definitely needs fixing:

(to ATA developers)
Any time an ATA command is issued outside of the SCSI layer, we need to employ a timer to time out commands.

Since most commands are done within the SCSI layer, which provides a lot of error handling apparatus, most commands properly time out. The ones during probe - IDENTIFY DEVICE, set xfer mode, etc. - do not have such a timer.
