Description
Running piglit tests against mesa-11.0-rc1 package in debian experimental
https://tracker.debian.org/news/707424
i have one test segfaulting the X server consistently.
HW is Ivy Bridge laptop with an additional GK107 (NVE7) kepler.
Xserver version: 1.17.2 (from debian sid)
mesa: 11.0-rc1 (from debian experimental)
libdrm: 2.4.64
kernel: 4.1.0
Test is ran via:
logging into X locally
then via ssh:
export DISPLAY=:0
xrandr --setprovideroffloadsink nouveau Intel
export DRI_PRIME=1
Verifying with
glxinfo | grep nouveau
just run the problematic test
bin/glean -t vertProg1
That immediately crashes the X server with a segfault
an attached gdb show following backtrace:
