I had Mesa snapshot from 2016/11/09 running fine but with one from 2016/11/25 I have Xorg lock-up. 5248 tty7 Dsl+ 0:06 /usr/lib/xorg/Xorg -nolisten tcp -auth /var/run/slim.auth vt07 All other processes run fine, I can connect pc using ssh, but Xorg does not react to keyboard (C+A+F1, C+A+Bs), so the only way to restore system is REISUB, even after reboot command the system doesn't reboot, the screen is blanked so I don't see what's going with it. I tested this issue only with Black Mesa game from steam. I can provide the last 20 lines of strace -p <Xorg's pid>, but they look useless. After git bisect and patch -R I've found a commit causing this issue: bf75ef3f9201e11bb08a4d03dab20d5ff86f1ebc Author: Marek Olšák <marek.olsak@amd.com> 2016-11-15 23:15:55 Committer: Marek Olšák <marek.olsak@amd.com> 2016-11-21 23:44:35 Parent: ef6c84b301ce15022d4907dfb0db5764e31e68f5 (radeonsi: eliminate VS outputs that aren't used by PS at run time) Child: c5a654786b5b68c5c215e3bd1bc83b02d7e2a0e9 (swr: [rasterizer memory] minify original sizes for block for mats) Branches: debian, master, remotes/origin/master Follows: 13.0-branchpoint Precedes: radeonsi: remove all varyings for depth-only rendering or rasterization off Tested-by: Edmondo Tommasina <edmondo.tommasina@gmail.com> Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com>
