i might not be much help on this but here's some info.

---if it were me, i would update my bios/uefi.

---from your log output we see(lines 870 & 871):

"[ 9.863404] nouveau 0000:01:00.0: Direct firmware load for
nouveau/nv117_fuc409c failed with error -2
[ 9.863409] nouveau 0000:01:00.0: Direct firmware load for
nouveau/fuc409c failed with error -2 "

---so this might be useful:

---i would, of course be sure to double check everything on the arch
nouveau wiki page

good luck
