Created attachment 115212 [details] [review] drm/i915: fill scratch page Created attachment 115222 [details] [review] drm/i915: Workaround to avoid lite restore with HEAD==TAIL The first patch should release the client, so fix the 'doesn't exit testing' part. The second patch should fix the problem that the test hangs in the first place. Please test both, separately. Test 2 rounds on the latest kernel with first patch, this case will causes system hang when running fifth and sixth time, if enable the serial console,the system can not boot up. Test 2 rounds on the latest kernel with the second patch , this problem will appear when running third and eighth time. Test the both patchs for 2 rounds, this case will causes system hang when running third and eighth time. BTW,this problem doest not exists the BDW GT3. Created attachment 115288 [details]
dmesg(SKL)
Also reproduce it on SKL. Fail rate:2/5.
leave it run 20 minutes, it doesn't exit testing, reports following warning:
