I need to kill firefox, or better the X session to get it back to normal. THe logs don't show any strange output top's top process: 27021 norbert 20 0 1351536 449868 88788 R 100.4 5.6 4:46.16 iceweasel 35 root 39 19 0 0 0 R 100.0 0.0 2:41.10 khugepaged Switching back to 3.17 does Not* exhibit the same behaviour. Is this a bug in Firefox/Iceweasel, or is there something luring in the kernel.
