Your 3.12-rc2 lod looks incomplete - note the timestamps.

AFAICS the only commit that should be affecting you is
commit a27e56996687e79416d69a7e6dc26f9d8fe06059

    drm/nouveau: use MSI interrupts

    MSIs were only problematic on some old, broken chipsets. But now that we
    already see systems where PCI legacy interrupts are somewhat flaky, it's
    really time to move to MSIs.

    v2 (Ben Skeggs): blacklist BR02 boards


You should be able to toggle MSI off using "nouveau.config=NvMSI=0" appended to
your kernel command line. Can you give it a try and attach the resulting dmesg
