Comment # 41 on bug 103370 from Robert Liu

So far, setting max_sclk to 60000 and max_mclk to 80000, the system passed a
24hours burn-in test (vblank_mode=0 DRI_PRIME=1 glmark2 --run-forever).

Another issue found is when removing the adapter, the system goes to suspend.
After I wake it up, it continues running the benchmark.
