Just about everyone is seeing this with the new EH code and current
libata. If you back out the EH changes life seems to go back to normal.

If you're talking about phantom device problem, it isn't related to EH itself. It's because of irq-pio which was merged together with EH and the fix is polling IDENTIFY.
