Public bug reported: Have two machines with same chip (Radeon XPRESS 200M), this one running XUbuntu 14.04 (with Utopic driver) and other one running Mint 17.1 XFCE (apparently with LTS driver). Both exhibit same random freezing.
When frozen, fans spin more and more (CPU on 100%, generating heat?), not possible to switch to console, no sysrq-combinations work, nothing out of the ordinary to be found in the logs afterwards. Have Memtested, checked SMART-info. I tried linux-crashdump on the Mint- machine but I couldn't find any file it would have created. Maybe it didn't.
