I recently upgraded an HP dv7-6b63us notebook (dmesg below) to amd64/mp 5.1-current as of about 11:30 EST 25 February 2012 (rebuilt from source several times since installing a 7 February snapshot) and have started seeing
ahci0: attempting to idle device ahci0: couldn't recover NCQ error, failing all outstanding commands. messages on the console and in the dmesg buffer; their timing doesn't correlate with anything obvious to me. If anyone has test code to run or other suggestions for how to track this down I'll be happy to help.
