Comment 40 for bug 1109309

Hi Joseph,

Hm,, results with 3.9 are inconclusive :/ As it pertains to this bug, I *don't* get a kernel panic first thing after booting. But I see the following:

- On boot-up, the system which is set to auto-login is unable to do so. After a while it dumps me back to lightdm. If I try to login, I see a plain background with movable cursor, after a while it goes back to lightdm, looking like compiz/unity are unable to start.

- I see a bunch of messages like this on dmesg:

All in all, it's hard to tell; I'd say the original bug is no longer present but nouveau has some other bugs that cause this system to still be unusable.
