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 !

The Kernel reports constantly about a NULL pointer reference. Sometimes the X-server and the Unity desktop is started, but the UI freezes constantly for a few seconds. It often ends with a complete freeze of the computer. Other times the computer freezes before the desktop was loaded. This bug report was created with the information of the Ubuntu 14.10 32bit live disk, but I also encountered the same problem with the Ubuntu 14.10 64bit live disk. I think it could be the radeon driver for my ATI Mobility Radeon HD 5650.
