Hi, Christian:
Thanks very much for you so fast reply. I will try this commit patch first. My kernel version is 4.19.36(for some reasons, this version should not be upgraded).

主题: Re: Bug: amdgpu drm driver cause process into Disk sleep state
please update your kernel first, cause that looks like a known issue
which was recently fixed by patch "drm/scheduler: use job count instead
of peek".
Probably best to try the latest bleeding edge kernel and if that doesn't
help please open up a bug report on https://bugs.freedesktop.org/.
Regards,
Christian.
