Hi,

I hope I'm posting this in the right place.

Linux 2.6.0-test8 crashes when I try to switch to another console. I get this
message: "nable to handle kernel paging request"
(I'm not sure where the `u' is. :)
As far as I can tell, it has something to do with the neofb-driver.

Hi,

the stack trace shows that it crashes in neofb_imageblit() which was added by James Simmons, I've CCed to him and the kernel mailing list.
