i found a case yesterday where an ahci drive would not be recognized because it had gone into an intermediate power saving mode before we could talk to it. i hadn't seen this power-saving mode before. hotplugging the same drive worked just fine.
is anyone else seeing this problem? (you can verify by "echo state reset>/dev/sd$baddrive/ctl" which should bring the drive to life; also the sstatus in the ctl file should be 211.) this is an atom ich7r motherboard in case that jogs anybody's recollections of heartache. if so, would you mind verifying that my fix works for you? please contact me off-list. - erik
