I should think it should have.

I think we're too aggressive about disabling the libata ACPI support, 
even. One of my laptop's _GTF commands on resume is a DEVICE 
CONFIGURATION FREEZE LOCK command, which gets rejected by the drive 
(maybe it worked on the original Hitachi disk, but I've upgraded it to a 
  newer Samsung). I'd say if the drive returns command aborted on one of 
these, we should just ignore that command and continue to the next one 
without trying to retry or disabling the ACPI support entirely.
