Created attachment 114233 [details] dmesg After 30 minutes or so my display goes black and I can see my desktop environment (KDE) crashed in dmesg. See attached dmesg and Xorg.0.log. Please ignore all the v4l related noise in the dmesg as it's from a custom compiled kernel and not the stock Arch Linux kernel I'd normally use. This has both happened with kernel 3.18 and 4.0-rc3. The severity increased on the upgrade to xorg 1.17 OS: Arch GPU: Advanced Micro Devices [AMD/ATI] Tahiti XT [Radeon HD 7970/8970 OEM / R9 280X] Display Type: Display Port

Some other possibly helpful info. I left my login manager (sddm) sit until the screen went dim due to inactivity. I moved the mouse around to wake it back up. My monitor notices the card trying (the OSD kicks in), but my screen stays black. Any attempts to restart X or get the display back results in the same behavior. The only solution is a hard reset.
possibly a duplicate of bug 89431. Can you try the patch on that bug?
(In reply to Alex Deucher from comment #3) > possibly a duplicate of bug 89431. Can you try the patch on that bug? Same behavior after 5 attempts with kernel 4.0.
I believe I've been able to pin-point the cause of this crash. I re-installed Arch as a last ditch effort to bring stability to my desktop. However, this time I did not install the Infinality patches (https://wiki.archlinux.org/index.php/Infinality). I've had 0 X crashes after a week of heavy usage. Feel free to close if you believe this is an isolated issue.
