Want to share this in case it helps anyone else. I stumbled across this issue after putting together a new Ryzen 2200G HTPC with AsRock AB350 M-ITX mainboard a few weeks ago. Would encounter random freezes every couple of hours.
After updating UEFI to latest version, updating kernel to latest 4.19-rc8, and Mesa to 18.2.2, I was still having stability problems (freezing with error messages in dmesg output). Made the changes in BIOS to typical current IDLE etc. and still was having issues.

But then realised I had not updated the amdgpu firmware, so grabbed the latest version from https:/ /git.kernel. org/pub/ scm/linux/ kernel/ git/firmware/ linux-firmware. git and everything seems to have been stable since then *fingers crossed*.
