I am seeing something similar with the released 11.04 distribution. The symptom is that I'll leave the computer running and when I come back it is hung, either with a black screen or a frozen screensaver. The only way I have found to recover is a power cycle. Browsing the logs, I see the following two lines repeated every 1-2 seconds:
