the problem has appeared at the end of January. Since then we (linux
distro geexbox mainteners) have tried all intel drivers (2.6.X ), kernel
(2.6.29[rcX]) with no luck.

At the beginning we thought that it was a distro related problem, but we
receive failing report only for intel cards, all other xorg drivers seem
to work fine.

for the record we're up to date for all related stuff : mesa 7.3, libdrm
2.4.5, xorg 1.6.0

to answer you the dmesg log with a 2.6.29-rc8 kernel :
http://pastebin.com/ma99fb07 (it's basically the same as what we have with
2.6.29 kernel)

as the stack trace speaks of gem we think that it could be related to gem
integration in the kernel, but it's just a guess

David
