Yes, it may also be good to test on different configurations, the original
patch fixed hotplug related
problem where 6Gps drives connected back at lower speeds.

I not sure upstream will let us change the value of mask.
Will you get the same result of you set sata_spd_limit?
link->sata_spd_limit = 0x7
I believe that corresponds to 6Gbps but I don't see a #define
we can use.
Also, is the comment accurate? Before you started debugging
did you see a hard r
Ok thanks, please look at this some more, I will try to get back with
you soon.

Hi,
May I ask for one more test? Looking at the code some more, I don't think I can
just remove
the return. The root of the problem is hard reset fails and
sata_link_hardreset() is never able
to reconfigure the speed. This patch sets link->sata_spd_limit before
returning, I have been

Hi,
I think the fix is removing the "return" and letting the code fall through in
sata_down_spd_limit().
Please give me some time to review the latest log, and I will need to
reconfigure a couple of local
systems and re-test with that change. Thanks.

Hi Joe,
The original intent of the patch was not forcing a 6Gbs drive down to
1.5Gbs after hotplug.
Noting,
SSTATUS = 275 = 0x113 = 0001 0001 0011
That corresponds to ACTIVE PM STATE | GEN1 SPEED | DEVICE DETECTED
spd = 1 (corresponds to 1.5Gbps)
One question, the print for mask came after th
Ok, thanks, please let me look through the output.

Hi Joe,
Can we put some debug in sata_down_spd_limit() and see some of the values
for spdlimit, sstatus, spd, mask, right before the change to not force the mask.
Also, can we track the exact path of calling sata_down_spd_limit().
The the intent of the patch was not to force the speed down before
