The last lines are repeating over and over. Keyboard no longer functional.
Mouse still working, but server not reacting to clicks.
Everything works fine under kernel 2.6.27.7. Kernel 2.6.28-rc7 shows the same
problems.
Steps to reproduce:
Start X on described system and after a few seconds to minutes above behaviour
occurs.
