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.</pre>
