Date: Wed, 28 May 2014 18:25:21 +0100 From: Ken Moffat To: Daniel Vetter Cc: Dave Airlie , linux-kernel@vger.kernel.org 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.
