Created attachment 131259 [details] bisect-protocol.log Environment ----------- OS: Gentoo Linux (several kernel versions) GPU: AMD, Inc. [AMD/ATI] Tahiti LE [Radeon HD 7870 XT] [1002:679e] Driver: tag xf86-video-amdgpu-1.3.0 and master Description ----------- With driver beyond tag xf86-video-amdgpu-1.2.0 (precisely from commit b5c18947) I got a “Segmentation fault at address 0x0” on Xorg start. Probably the mentioned commit is the culprit. See my attached bisect-protocol.log but be lenient with me — it’s my first bisect log. Thanks in advance and please let me know when I can do something more within the limits of my resources. Addendum -------- FWIW: I was never be able (for nearly three years) to get hardware acceleration to work with this GPU and the open-source driver. Therefore the setting: Option "Accel" "no" is currently and must always be applied. Otherwise the screen goes black, keyboard and mouse will be lost after invoking `startx`. Thus, only a hard reboot remains to get access again and SSHing into this PC is useless because I have no clue how to debug those behaviour.
