回复： Bug: amdgpu drm driver cause process into Disk sleep state

[78666679]

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).

Hi Yanhua,

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.
