I've not seen any problems, suspend and resume worked correct so far.

I see same error message in dmesg with kernel 3.11-rc5 when my notebook is suspending or hibernating. But suspend and hibernate working fine. I have Radeon HD 6470M card.

This is printed with my Barts GPU as well, which seems to indicate that
the function is slightly misnamed.

Bug still persist in  3.18.1 kernel. And it's very annoying, because in
my laptop(Radeon HD5400) I cannot return from suspend/hibernate because
of this bug, and I need to restart computer...

The code is shared across several generations of hardware.  As long as
suspend and resume works ok, it can be ignored.
