AFAIK, nvidiafb is part of the Linux kernel, not of the nvidia driver. According to this page: http://wiki.gentoo.org/wiki/NVidia/nvidia-drivers - the MTRR error is due to the fact that you disabled MTRR in the kernel configuration, probably because you disabled IOMMU - using the nvidiafb module with the nvidia proprietary module is not recommended, as they are known to conflict at times. > > In debian systems, adding > blacklist nvidiafb > > to/etc/modprobe.d/nvidia-blacklists-nouveau.conf > > solve the issue. > > xenomai has some kind of issue tracker?
