I tested the upstream kernel on my current Ubuntu 14.04 installation, but still get the same issues. linux-image-3.19.0-031900rc6
The following packages were used: linux-image-3.19.0-031900rc6-generic_3.19.0-031900rc6.201501261152_amd64.deb linux-headers-3.19.0-031900rc6_3.19.0-031900rc6.201501261152_all.deb linux-headers-3.19.0-031900rc6-generic_3.19.0-031900rc6.201501261152_amd64.deb from this location: http://kernel.ubuntu.com/~kernel- ppa/mainline/v3.19-rc6-vivid/ I also installed a new linux-firmware package, because otherwise the kernel installation would log some warnings about missing firmeware files for the radeon module. I used the package from 14.10: http://packages.ubuntu.com/utopic/linux-firmware linux-firmware_1.138_all.deb This is the first stack trace I get: [ 20.620150] WARNING: CPU: 2 PID: 154 at /home/kernel/COD/linux/drivers/gpu/drm/radeon/radeon_gart.c:234 radeon_gart_unbind+0xda/0xf0 [radeon]() [ 20.620151] trying to unbind memory from uninitialized GART !
