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
