completely at random. The Xserver stops redrawing anything but the mouse is
still moving (hwcursor). I could login through ssh from another computer and
attach gdb to the server, to find me inside a tight loop in

time. After killing and restarting the server I reliably get a hard lock (ssh
server stops answering my requests, kernel hangs).
