I'm experiencing the same problem, if not similar enough: suddenly, most applications freeze for a couple of minutes and then unfreeze. dmesg doesn't show any messages for the moment of the problem. My system is fully updated. The PC is new, so I haven't run any previous version of Ubuntu on it. Let me describe three instances of the problem.
Instance 1: Some applications froze. Mouse is NOT frozen, keyboard is NOT frozen. System monitor app stopped updating. A terminal still responds. I was trying to kill pulseaudio when gnome-terminal froze after a tab completion, right after hitting tab but before the beep or the actual completion occurred. Workspace switcher didn't freeze, some applications repaint others don't. Found another terminal and hitting tab froze it too. Eventually, my PC was unusable, and eventually, applications unfroze. I couldn't kill pulseaudio. Instance 2: A terminal still responds, I tried attaching strace to the pulseaudio process with no luck. top continued running. Pulseaudio was taking a constant 3% of a CPU, which seem pretty high to me. I have killed pulseaudio and the terminal froze. Eventually, they all unfroze. I killed pulseaudio. Instance 3: As I'm writing this (under Opera), my System Monitor applet stopped updating. I have a bunch of Link Monitor applets too, and they seem to be updating correctly. The workspace switcher (with 3D effects diabled) is still working. It lasted about 30 seconds. I didn't try other applications this time. Now it is updating again. System is Jaunty 64-bit, fully updated.
