-Other random notes (do outside the NCQ branch):
------------------------------------------------------
-implement support for PM FIS-based switching, remove restriction in atastart()
-for hw which supports it, adjust error handling in controller drivers to handle
-xfers for several different drives
-
-dump to unopened disk fails (e.g. dump do wd1b when wd1a not mounted), due
-to the open path executing ata_get_params(), which eventually tsleeps()
-while waiting for the command to finish; specifically, if WDF_LOADED is not
-set 
-- happens due to wd_get_params() with just AT_WAIT in wdopen()
-- not easy to fix, open needs to read disklabel and all this mechanics
-  is too much for emergency crash dump code path
-- old bug - kern/16789
