vbios from /sys/bus/pci/devices/<pciid>/rom
Since kernel 3.13 nouveau fails to load with error -22.
Olso it reports an unknown opcode 0x80.
I suspect it fails to load becouse of the unknown opcode, since i have seen the
return code of the function checking the opcodes have changed in 3.13.
I have attached the vbios taken from /sys/bus/pci/devices/<pciid>/rom and the
dmesg from both kernel 3.12 and 3.14 rc7.
Could maybe a mmiotrace be helpful?</pre>
