I have nvidia nforce4 motherboard with nvidia sata controller:
..It looks like something is trying to issue a command to disable APM
power management on the drive, and the command fails (likely because
it doesn't support that command).
../sbin/hdparm -B254 $DRIVE
And that -B254 cause above error message in dmesg log. Output from
setting Advanced Power Management level to 0xfe (254)
APM_level = not supported
$ sudo hdparm -I /dev/sda | grep -i power
* Power Management feature set
However, these NVIDIA SATAs are black boxes, and rather buggy ones at that,
so it's possible there's an unknown issue there.
