Xorg.0.log, after several crashes X can't be opened/used anymore, device seems
unavailable

not sure if to post this here or in #79980, 

but when continuing usage after the gpu gets unstable with chromium-usage (so
using chromium in browsing in complex sites; chromium with adobe flash player
[youtube !]; chromium with HTML5 video [youtube] - seems to mostly accelerate &
more easily trigger the common issue with #79980 ?)

the following end-result is visible in the attached Xorg.0.log, the gpu isn't
accessible anymore and a system reboot is necessary


usage-pattern was following:

- firefox - browsing the web, viewing wallpapers, gmail, google plus
- gnote - writing notes
- switching between firefox and gnote

desktop environment used was Xfce4 + compiz-fusion; past experience has shown
that it doesn't matter whether composited or not (fluxbox, xfce4+compiz-fusion,
kde4+kwin, razor-qt + kwin); so no difference since opengl or webgl
acceleration is used anyway


(opengl); webgl might be something further to investigate - 

the "issue" is, however that all of this works in 99%-100% with 3.14 kernel for
me
