So, IMO it is an improvement, but it is definitely not a fix for

With a new copy of hdparm, use "hdparm -Q1 /dev/sd?"
Does that fix your "regression" ?
$ sudo hdparm -Q1 /dev/sda
/dev/sda:
setting queue_depth to 1
queue_depth = 1
Yes, that does result in the original behavior of the led.
(Using version 8.9 of hdparm.)
But that's not new information: we'd already determined some time ago that
disabling NCQ "fixed" the problem, both if it is done at runtime and when
it is disabled in the driver:

http://www.spinics.net/lists/linux-ide/msg25645.html
..
Still, that's proof that there is NO REGRESSION here,
so please stop using that term.
Older kernels had a working LED without NCQ,
and so do newer ones. No regression.
In the meanwhile, it appears that Saeed is working to determine
for sure that this is a hardware limitation, as it appears to be.
Cheers
