Public bug reported: Description: Ubuntu 12.04.1 LTS Release: 12.04
I ran apt-get dist-upgrade and moved from linux-image-3.2.0-30-generic version 3.2.0-30.48 to linux-image-3.2.0-31-generic version 3.2.0-31.50. Upon reboot I had a black screen. Even virtual terminals didn't work. Rebooting back to -30 made the machine usable again. After looking in /var/log/kern.log I googled for: radeon ubuntu 12.04 "GPU lockup CP stall" Several Ubuntu bugs came up with some random, some suspend/resume related and some boot video problems: 986524 936159 980019 This upstream bug indicates that a kernel change exposed a bug in the driver/mesa/drmlib : https://bugs.freedesktop.org/show_bug.cgi?id=45366 Attached is some relevant apport-cli --save results.
