   So, to handle the common cases better, libata EH times out resets

I think that 10 seconds timeout is just *slightly* too short.
There are drives here somewhere, that always fail the first attempt
because they take about 12 seconds to spin-up and begin communicating.

Also, ATAPI sometimes takes quite a while to respond, I've seen, when media is in the driver.
