--- Comment #2 from Holger Hoffstätte <holger.hoffstaette at 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.
