I have the same problem. When the freeze starts, the mouse is getting slower and slower, i can still minimize windows, but i cant start programs or do ctrl+alt+fX. Then after a few seconds the system freezes completely and my mouse does not move anymore. The only thing i can do is restart by pushing the button. The freezes happened when using firefox (watching videos via flash) and running retroshare. Its no memory leak or so because i got 8gigs and the memory-consumption applet shows that hardly any memory is used. Also the applet shows that my cpu (6 core) usage is low. I suspect it to be either the disk or the wireless. Probably the wireless because it only seems to freeze during heavier network usage, not disk usage. The system never froze while copying 50 gigs of data etc. Also, the wireless connection is lost sometimes and i can only reconnect to it by restarting.
