GPU dump error at /sys/class/drm/card0/error
I'm using WebKitGtk+ with my own JHBuild setting:
<a href="https://github.com/tanty/jhbuild-epiphany/tree/master">https://github.com/tanty/jhbuild-epiphany/tree/master</a>
Epiphany 3.20.3 and WebKit 2.13.91.
I'm running Epiphany with the dconf key:
"process-model" = "shared-secondary-process"
The compilation was done with CMake args:
'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_FLAGS_RELEASE="-O0 -g1
-DNDEBUG -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g1 -DNDEBUG
-DG_DISABLE_CAST_CHECKS"'
Just by opening the last closed session, the desktop gets stall, even when
there is, apparently, no high CPU usage.
I can see this in the logs:
$ less /var/log/kern.log
