For total clarity. The fixes here were not verified (as they did not fix the issue possibly after a BIOS update) and are therefore reverted in the kernel. When this closed shortly on release of the reverted kernel, that will be an error, and the bug will need reopening. We will retest against that base.

Test Case: suspend/resume (on affected hardware) Regression Potential: all upstream changes, triggering suspend/resume handling for these devices from a safer context, regression potential is relatively low. === I'm testing the new development branch (Vivid Vervet), which currently has the Utopic kernel 3.16.0-23-generic installed. (proposed repositories are enabled) This problem might be a regression, and it has been reported upstream: https://bugs.freedesktop.org/show_bug.cgi?id=81136 Problem: When I try to resume from hibernation the screen hangs and the GPU is locked. It cannot load the graphics properly. The monitor loses its signal completely. Testing: Blacklisting the nouveau driver and perform the following hibernate/resume test, seems to indicate that indeed the problem is nouveau, because the test has been completed successfully: # echo platform > /sys/power/disk # echo devices > /sys/power/pm_test # echo disk > /sys/power/state Mainline: The problem seems to be fixed in latest stable mainline kernel, for now 3.17.1-031701-generic (Utopic).
