One external screen connected to HDMI
Steps:
-------
1. Suspend to DISK with:
sudo -s
echo disk > /sys/power/state
2. Wait 60 seconds
3. Resume
4. Wait 30 seconds
5. Repeat previous steps several times
Actual result:
--------------
5. DUT reboots the 15th iteration without restoring any image, there is a GPU
hang:
[ 8.118322] sd 2:0:0:0: [sdb] No Caching mode page found
[ 8.118383] sd 2:0:0:0: [sdb] Assuming drive cache: write through
[ 445.825548] [drm:i915_context_is_banned [i915]] *ERROR* gpu hanging too
fast, banning!
Expected result:
---------------
5. DUT can suspend to DISK and resume 2000 times
Info
----
I used the script attached to automate it, execute command:
# ./suspend_stress_test.shell --iterations=100 --mode=disk --suspend=48-52
--wake=28-32 --abort=none --display=error --file=suspend-log
