Hi Max

A small additional info.
This error msg occurs during VBIOS parsing:
Oct 08 21:56:28 fractal kernel: [drm] nouveau 0000:00:12.0: Parsing VBIOS init
table 0 at offset 0xE2EF
Oct 08 21:56:28 fractal kernel: [drm] nouveau 0000:00:12.0: ======= misaligned
reg 0x001020FB =======
Oct 08 21:56:28 fractal kernel: [drm] nouveau 0000:00:12.0: ======= misaligned

Oct 08 21:56:28 fractal kernel: [drm] nouveau 0000:00:12.0: Parsing VBIOS init
table 1 at offset 0xE440

See complete (and somewhat censored) dmesg and Xorg.0.log attached. Although
Xorg log is scarcely relevant because these error messages do not seem to
correlate to any visible problem.

Closing this bug to not confuse people even more.

To state it clearly: the misaligned reg thing is no bug and normal on certain
chipsets. It is most likely not correlated to any (real) bug you may encounter
while using nouveau. Feel free to file bugs for any problems you have with
nouveau, but this isn't one of them.
