dmesg log with enabled nouveau debug

When the kernel tries to load the nouveau kernel module during boot, it fails
with "failed to parse ramcfg data"(see attached logs). It also happens when I
try to load the module manually later. This is a bug which occurred between
kernel 3.17 and 3.18(downgrading to 3.17 fixes the problem, each version above
doesn't work). I'm using nvidia gt645m(gk107) on a Lenovo z500 with intel
i5-3230 processor. OS: tested on arch linux(both stock & -ck kernel) and fedora
22. Let me know if any other info would be needed.
