** Description changed:

  I've tried "sudo strace -p $(pgrep X)" in a KDE konsole to see what Xorg
  was doing that may cause high cpu load.
  
  After a few seconds and lot of output, the system hung and I could not switch to another VT, but music kept playing in the background.
  Doing the REISUB sequence, the system restartet after Alt-SysRq-R or -E already.
  
+ This is probably related to the generated output, since it did not
+ happen on VT1 after reboot, where I've used "-o outputfile" though.

+ Using "sudo strace -p $(pgrep X) -o /tmp/1" and "tail -f /tmp/1" also
+ does not cause the hangup.
