Comment 612 for bug 359392

I got the same freeze again (with laptop screen closed) but without the syslog messages, so its probably not related.

My problem is not an immediate lockup like it seems that Jithin Emmanuel reported (though I haven't looked at the Xorg log yet) - if I just close the lid and leave it for a few minutes and open it again then its usually still ok. For me the freeze happens when I have the screen closed for a long time - several hours.
