DetailsDescription:
After suspend/resume X11 display is not working. Screen looks like snowing/static. In syslog various kernel, X11 and graphical application errors / core dumps appear. On most tries system can still be shutdown by pressing the power button. The kernel and mesa versions do not seem to matter much. Tried several and the behavior was the same. The weird thing is that it only happens when CPU hyperthreading is disabled in BIOS. With hyperthreading on it works. Additional info: * package version(s) linux 4.12.12-1 linux-lts 4.9.48-1 mesa 17.2.0-2 mesa 17.1.8-1 xorg-server 1.19.3-3 * hardware Ryzen 7 1800X Oland PRO [Radeon R7 240/340] * config and/or log files etc. GLX renderer info: AMD OLAND (DRM 2.50.0 / 4.12.12-1-ARCH, LLVM 4.0.1) See journal-errors.txt for relevant syslog messages. Steps to reproduce: - boot system with lightdm display manager - suspend system from lightdm menu - wake up system
