Comment 0 for bug 1080808

Upgraded to Raring; when booting using kernel 3.7.0-2-generic, a login to Kubuntu/Ubuntu fails with the errors shown in the attachments.

This has been happening since Quantal, around Beta2 -- on Quantal, I would have such a failure (or a GPU lock-up, like in bug 1048701) every so often: on Ubuntu, after a few hours, on Kubuntu usually on logout/login, or -- just once in ~ 2 weeks, during normal usage.

On Raring it seems guaranteed to fail *always* on login. Once failed, laptop has to be power-cycled for the display to work again.

Booting back on the current Quantal kernel (3.5.0-19) allows me to work again.
