Thanks for chiming in James! Few things I've observed since adding 'pci=noats' the graphic artifacts seem to happen way less. I did observe one lockup which required me to hard shut down the computer. This was a wake from suspend scenario.
I used to deal with somwhat similar issues here -- https://bugs.freedesktop.org/show_bug.cgi?id=110674 not sure if that's of any use. Let me know if a fresh bug is warranted.
Hi Anthony,
The s3 hung issue here always with error: AMD-Vi: Event logged [IO_PAGE_FAULT...] Bug:110674 don't have gfx ECC error. You case do have lots of them. Can you share the whole dmesg after you added pci=noats? Regards! James
