Have you checked for any output netconsole yet? A few old kernels? Optimistically this used to work and we can bisect the cause. (In reply to comment #3) > Have you checked for any output netconsole yet? A few old kernels? This machine can only use USB network adapter, with which netconsole can't work. > Optimistically this used to work and we can bisect the cause. Yeah,this is a regression. I bisected this: 4906557eb37b7fef84fad4304acef6dedf919880 is the first bad commit commit 4906557eb37b7fef84fad4304acef6dedf919880 Author: Rodrigo Vivi <rodrigo.vivi@gmail.com> Date: Thu Jul 11 18:45:05 2013 -0300 drm/i915: Hook PSR functionality PSR must be enabled after transcoder and port are running. And it is only available for HSW. v2: move enable/disable to intel_ddi v3: The spec suggests PSR should be disabled even before backlight (by pzanoni) v4: also disabling and enabling whenever panel is disabled/enabled. v5: make it last patch to avoid breaking whenever bisecting. So calling for update and force exit came to this patch along with enable/disable calls. v6: Remove unused and unecessary psr_enable/disable calls, as notice by Paulo.
