Hi Ashok,

sorry for the delay, I was swamped with work in the first quarter and am
in the process of slowly going through my backlog...

(a) Correctable error (Receiver Error) after powering off => harmless.

(b) ASPM L1 enabled on boot, but disabled after powering off and back on
    => I believe Sinan is working on this (+cc).

(c) Autonomous Bandwidth Status is set after powering back on, but the
    speed and width is the same as on boot => harmless.

(d) PME Status is set after powering off and stays set after powering on.
    Weird.  Could you retry with the new pciehp runtime PM series I sent
    out a few hours ago?

Thanks!

Lukas
