This system is a console system, X is only used sometimes. So while there 
may be updates of other components (it is Debian testing after all) the 
problem occurs in console mode without running X or mesa.
And rebooting the old 3.5 kernel solves the problem.

Not without some help,. I’m no programmer. You probably mean I should 
test different git commits?
