[amdgpu] ryzen 2500u random Xorg freeze

[njklim]

Currently using a Dell Inspiron 3835 with a ryzen 2500u with 8gb of ram on a pcie nvme ssd. PC randomly freezes at times. This actually occurs on asus x505za also running 2500u.

I checked the log files and there was this error.
[drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process gnome-shell pid 10648 thread gnome-shel:cs0 pid 10654
[drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process gnome-shell pid 10648 thread gnome-shel:cs0 pid 10654

I think it may be a problem with gnome since I was running lubuntu before and there's no hang whatsoever when using that.

Please test latest mainline kernel:

Currently using kernel version 5.4.3 with lightdm as display manager.I also installed amdgpu pro drivers. I've added idle=nomwait and iommu=soft to grub. Everything is stable so far.
