dmesg output: system boot + a couple of S3 suspensions + a S4 hibernation

Opening this as suggested in bug #67161 comment #6.

Running Fedora 19 with a live USB on an old system with Creative Labs Graphics
Blaster Riva TNT:

Linux localhost 3.9.5-301.fc19.i686 #1 SMP Tue Jun 11 20:01:50 UTC 2013 i686
i686 i386 GNU/Linux

If I run dmesg I see some errors like:

[    5.213896] nouveau E[   VBIOS][0000:01:00.0] 0x012e[ ]: unknown opcode 0x43

or:

The "unknown opcode" error appears at boot and waking up from S3/S4.
Regarding the protection fault lines, it seems like they appeared on boot and
on one of the wakeups from S3.
