Hello Christian,
I just checked with a laptop which has a dedicated nVidia Quadro 3100M
(Dell Latidude E6510), which has also world and kernel build with CLANG.
I do not experience this pagefault on that laptop either. I also have a
box running nearly the same hardware and the same GTX560Ti, but FreeBSD
10.0-CURRENT, and this box' OS is also built via CLANG. There is also no
issue. Maybe it's an BIOS issue triggered by the BIOS.
I guess, I can not circumvent any debugging ...

Thanks,
regards,
Oliver
