I also experience a hard system freeze; blank black screen (still backlit), network/ssh dead, console/alt-ctrl-fn unresponsive, hd activity light frozen. Using screen remotely to tail a console via ssh from another system I have seen no output in dmesg/messages/syslog to indicate an issue or that the freeze is related to this specific error, however I have my suspicions. The freeze happens about twice per week, though twice already today prompting me to have a closer look.
