Public bug reported:
System freezes after random time, sometimes after hours, sometimes not. When
freeze, need to switch off power.
No freezes any more after removing /usr/lib/xorg/modules/extensions/libglx.so.
I dind't find anything in system logs.
System was upgraded from 14.04 LTS to 16.04 TLS. With 14.04 no freezes. Other
linux running well (double boot).
Tried a few things before finding cause, e. g. disabling swap, changed from KDE
to LXDE, I also tried kernels 4.6.0 and 4.6.5.
