Public bug reported:

Binary package hint: xserver-xorg-video-intel

The commercial robot simulator Webots (free demo version at
http://www.cyberbotics.com/products/webots/download_linux.html) recently
switched to Ogre for their rendering engine.

Since then the 64 bit version of Webots will freeze the system (even
Alt+Print+K won't restart the X server, I need to poweroff the maschine
manually). The 32 bit version works fine under the same 64 bit system.

This is the last message from the command line (subscribed to a good old
sheet of paper):

do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working
correctly. Try adjusting the vblank_mode configuration parameter.

Webots might use reflection in their rendering internally (I have
contacted the vendor about that) and this bug might be related to
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
intel/+bug/298532. But in #298532 the reporter explicitly mentions that
both 32 bit and 64 bit versions will crash.

I know that Ubuntu is not in charge of fixing bugs triggered by some 3rd
party commercial application but the system, but no application should
be able to freeze the complete system causing data loss and potential
file system integrity problems.
