During Ubuntu hibernation the following messages appear on the screen and they are accumulated until the system is completely restarted. They also can be found in
[50357.815787] [drm] nouveau 0000:01:00.0: 0x7241: i2c wr fail: -6 [50357.819721] [drm] nouveau 0000:01:00.0: 0x7253: i2c rd fail: -6
The hibernation itseld is working good (after hacking described in this article).
What do these messages mean and should I do anything to avoid them?
My computer is ASUS U40S, Ubuntu 12.04 LTS x64.
