Looks like a radeon issue, move there.

--- Comment #2 from Holger Hoffstätte <holger.hoffstaette@googlemail.com> ---
This (and similar) messages were supposed to be fixed by commit:
http://cgit.freedesktop.org/~airlied/linux/commit/?h=drm-fixes&id=49abb26651167c892393cd9f2ad23df429645ed9
(should be in the next -stable), but merging that into my 4.1.12+ kernel hasn't
fixed anything.
After reading the patch it seems that the sysfs_initialized flag is only ever
set to true when the last sysfs entry was successfully created; in my case that
particular setting (dev_attr_power_method) seems to fail, so the "all is done"
flag is never set. For some reason I get the "power method" failure message 4
times on each resume.
ISTM that setting the sysfs_initialized flag should be independent of previous
failures; do it once and then stop.

This was wrong, sorry. I get each sysfs failure once (4 in total).

Unconditionally set sysfs_initialized
This patch removes the conditional around setting sysfs_initialized and works
for me - no more spew on resume. Also fixes a previously duplicate message
text.

So it turns out that *in my case* - even with the original patch - these
messages apparently (?) were caused because my monitor was dying
(it's completely dead now) and reacting too slowly, i.e. not waking up
properly.
I got a new one and now the original patch - which is in 4.1.13 - does
indeed work fine: no more errors on resume.
