[Bug 258059] Re: Upgrade to Intrepid broke X (I830WaitLpRing timeout)

[Sabin Iacob]

in my case, X works fine for a while and then crashes when I start
Mozilla Thunderbird; subsequent attempts by gdm to restart X fail and
the screen is unreadable (looks like it sets a wrong refresh rate or
smth... all static and lines - also on text console, when switching to a
text console I catch a glimpse of the dialog box that tells me X keeps
crashing (I think))

Sometimes a restart solves the issue and Thunderbird starts fine afterwards, sometimes it takes 3-4 restarts.
relevant lines from /var/log/messages:

Also attaching Xorg.0.log (the last crashed one... I have yet to find a
way to keep it from restarting like crazy, other than running with
startx, that is)
