   I think that's a shame to have such a "error recovery" in one of the basic
drivers. ATA driver gives absolutely no clue about the reason of the failure
and just disconnects device. I'm curious why the driver behaves in this way.
If SATA code is just raw, it definitely must be corrected to implement proper
error recovery. If SATA specification is written so purely that proper error
recovery is just impossible (I really doubt if it's so), then SATA hardware
should be simply avoided in mission-critical applications.
