Hi
I am unable to get any kernel beyond the 3.16 branch working on an

Does reverting b0345bbc6d09 change anything?

So the bug is in the 4xx MSI code, and has always been there, in fact I don't
see how that code has *ever* worked. The commit you bisected to just caused the
existing bug to cause an oops.
Can you try this?

Thanks.
This works with 3.17-rc1. Will try with the 3.18 Branch .
OK great.
Any ideas why drm is not working ? (It never worked) .
No sorry. You might have more luck if you post a new thread to the dri list.

I'm curious why it's failing to allocate MSIs. Possibly it's just run out.
Can you post the output of 'cat /proc/interrupts'?
cheers
