[Bug 396048] [NEW] X restarts randomly, sometimes machine crashes

[Martin Emrich]

Public bug reported:

Binary package hint: xserver-xorg-video-intel

Since upgrading to kernel 2.6.31, my X session sometimes just restarts.
I am in the middle of typing, hitting a key, and immediately the screen
goes black, and most of the time the login window appears (Just as
hitting CTRL-ALT-BS). Sometimes, the screen just goes black and the
machine freezes completely (Caps Lock LED blinks).

I am running current karmic amd64 on a Thinkpad X200 (Intel GMA 4500MHD)
