Created attachment 100983 [details] /var/log/messages I use suse 13.1 xorg 7.6.1 mesa 10.2.1 Since kernel 3.15, suspend to ram don't work.

Bisect would be great. There were a ton of PDISP changes that went in, but they were largely no-ops (things to make debugging easier, etc).
i updated to 3.15.1 and i suspend to ram work again.
(In reply to comment #2) > i updated to 3.15.1 and i suspend to ram work again. https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/log/?id=refs/tags/v3.15.1 Seems unlikely that one of those commits would have fixed anything vs 3.15... issue is probably still there, just doesn't repro 100% of the time.
