The system is an optimus system, currently I am unable to use the Nvidia gpu at
all.

DRI_PRIME=1 hangs for a couple of seconds, followed by a fallback to the intel
gpu.

Currently running fedora rawhide

Can you grab me the following things please:

1) dmesg log of loading nouveau with "modprobe nouveau
debug=bios=trace"
2) mmiotrace of loading nouveau

Thanks,
Ben.

mmiotrace_nouveau.xz

System hangs whilst trying to get an mmiotrace of nouveau. 

I was able to get this by writing it out directly to the block device /dev/sda

xz is unable to decompress the file, unfortunately.

Oops, my apologies.  Can that be with "debug=bios=trace,devinit=trace"
?

For future reference, and to help others. I've been able to get the card to
boot using 

karolherbst/stable_reclocking_kepler_v5_4.7
fd1d9d32f8bc3a0e93306bc5044fb67694445e5e

and module config
runpm=0 config=NvClkMode=7
