Hi,
I have a kernel crash with _intel_ drm driver on Acer LCi291 laptop with builtin Intel 855GM card
when I start /usr/bin/X (it does work when "vesa" instead of "intel" drm driver is called from
xorg.conf, though).

There is a similar kernel crash at http://forums.gentoo.org/viewtopic-t-832282-start-0.html .


Thanks for clues,
