I've been having this little problem with the intel-gfx driver for a couple
months at least. Basically the xorg intel driver crashes with these errors:

(WW) intel(0): i830_uxa_prepare_access: gtt bo map failed: Cannot allocate memory
(WW) intel(0): i830_uxa_prepare_access: gtt bo map failed: Cannot allocate memory

After a little google, I've found the following, seemingly similar issues:

http://www.pubbs.net/201001/mandriva/43247-cooker-x-crashing.html
http://lists.opensuse.org/opensuse-bugs/2010-04/msg01805.html

This crash happens every few days, most of the time when I'm not even using
the laptop, and the lid is closed, but today it happened while I was
working. Was somewhat interesting to see things just disappear.

I've been trying to track this issue down for a while, someone said it
might be an app leaking pixmaps, but I haven't seen xrestop show more than
80MB of pixmaps for quite a while. Also, it usually occurs some time after
graphics start getting really slow (though this last time I didn't really
notice things getting slow). Talking a second or two for window or
desktop switching. At no time was there any errors or warnings in dmesg
related to this, nor was I running out of memory according to "free" or
the plasma system load viewer applet. Usually I had 1-2GB of ram available
(not including cache).

Thanks.
