If X makes use of DRI the whole system freezes. >How-To-Repeat: On a multiprocessor system configure a 5.4-STABLE for SMP, then add the line Load "dri" in xorg.conf and run X. After a few moments of use the system freezes. The exact activity that triggers the bug is not known but a few open windows are usually enough.
