Hmm. I was slowly getting ready for doing the bisect, but it seems
someone did it for me.

Subject: Resume from suspend broken in 3.15. (bisected)
User-Agent: Mutt/1.5.23 (2014-03-12)

I manually reverted 25f397a429dfa43f22c278d0119a60a343aa568f and it
seems I'm back at working suspend/resume in i915.

The 3.15 regression seemed to be "if suspend works once, it seems to
work until reboot", otherwise it failed in cca 70% cases. I did two
reboots so far with 25f... reverted, and it seems to behave ok.

Best regards,
