With some uptime I eventually start getting these GPU VM faults:
[106098.543115] VM fault (0x0c, vmid 6) at page 58321, read from TC (68) [106098.543119] radeon 0000:02:00.0: GPU fault detected: 146 0x0a0c480c [106098.543121] radeon 0000:02:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x0000E3CB [106098.543123] radeon 0000:02:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0C00800C
It's always the same fault number but the memory addresses(?) change.
See attached dmesg.
My system doesn't crash, but black glitches do appear on the screen and I need to switch desktops or move windows around to make them go away.
KDE desktop with compositing enabled.
I'm running Arch Linux with latest stable packages:
Linux carrier 4.5.4-1-ARCH #1 (closed) SMP PREEMPT Wed May 11 22:21:28 CEST 2016 x86_64 GNU/Linux
Name : xf86-video-ati Version : 1:7.7.0-1
P.S. I use pci=nommconf because I have massive issues with PCI-E devices otherwise (radeon goes nuts coincidentally).
