I've seen it happen with kernel 3.8-rc2 and SNA using the latest intel driver from git.

The hang isn't always the same:

* Sometimes it locks the computer up completely, requiring a hard reboot.

* Sometimes it locks X, but CTRL-ALT-F1 and back unlocks it.

* Sometimes it resolves itself without me even noticing that it has happened, other than that there may be some corruption in the tabs' title text in chrome and window movement has become somewhat jerky instead of the normal smooth movement you get after restarting X.

Next time it happens I'll see if I can recover any information.
