--- Comment #47 from James Zhu (jamesz@amd.com) --- Hi Jerome, Thanks! I knew this issue is not easy to judge if it is fixed. Since it occurred quite randomly. On my setup, this WA passed 5 times up to 300 suspend/resume cycles, 1 time up to 3800 suspend/resume cycle. But I doubt that it is root cause, so I took it as WA. But it seems it is not WA for all system. James
