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.

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.
