Last modified: 2012-08-23 08:24:09 UTC
screenblanking on my thinkpad x61 occasionaly never returns. dmesg has [ 7076.696056] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [ 7076.696067] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state [ 7076.697356] [drm:kick_ring] *ERROR* Kicking stuck wait on render ring [ 7076.697778] [drm:init_ring_common] *ERROR* render ring initialization failed ctl 00000000 head 00000000 tail 00000000 start 00000000 [ 7076.698348] [drm] Changing LVDS panel from (+hsync, +vsync) to (-hsync, -vsync) full message attached.

this annoying, i need to reboot my X61 Thinkpad every hour :(
same here
I need: a. the device ID of the GFX chip (second line of lspci -n) b. the machine itself to debug this. Did this work with an earlier version of the kernel? If it did bisecting would probably be the best chance to find the origin. Intel hardware has the tendency to hang only the latest can reliably be reset to a state to make it work again. I have numerous bugs with this across almost all gens of hardware.

Did not have any intermediate kernels.

It is not even clear that this is triggered due to a kernel change. Something else in the desktop may have changed which is triggering this issue. It'd be important to break down which application is triggering this. I've just installed a box to investigate the same issue on GEN2 hardware. I may be able to dig up some GEN4 hardware and could try to reproduce this there.
This is very likely an dup of #768584. *** This bug has been marked as a duplicate of bug 768584 ***
