Date: Thu, 4 Oct 2012 16:56:06 +0200 From: Daniel Vetter <daniel.vetter@...ll.ch> To: Miles Lane <miles.lane@...il.com> Cc: LKML <linux-kernel@...r.kernel.org>, Eric Anholt <eric@...olt.net> Subject: Re: 3.6.0+ (GIT) -- WARNING: at drivers/gpu/drm/i915/intel_display.c:1271 intel_disable_pipe+0xab/0x12e() -- plane B assertion failure, should be off on pipe B but is still active This should help: https://patchwork.kernel.org/patch/1436231/ It's not merged yet since it cause a black screen on resume on one of my really old machines. Issue isn't new at all, but the new modeset code is _much_ more anal about cross-checking the hw state with what we expect to be there.
