Added more appropriate people to this. Added both i915 and nouveau

Guys, any ideas?
Paweł, could you perhaps get a photo of the oops and post it
somewhere? I'm assuming the oops happens early during boot and you
never get a usable machine with dmesg - but if you do, then please do
post the whole dmesg too.

Hi Linus,
You must have missed the oops that was attached to the mail:
http://www.spinics.net/lists/kernel/msg1420355.html
Paweł, could you try the attached patch please ?
Martin
