Try latest 3.6-rc4 kernel, should be fixed there. – user87211 Sep 3 '12 at 7:27

Problem solved. Needed to add nomodeset to the boot parameters.

Here's a link to a thread with solution:

I had this error while testing 12.10 alpha 3 and had to place 'xforcevesa' in the boot command line to get a screen, but once installed it seemed to clear itself.

thanks for the reply. im a ubuntu noob, im not sure exactly how to do that. when these errors are being displayed, its a running process, where i cant enter anything. is there some key i should hold/press when i try to boot? – kevin chapman Sep 4 '12 at 0:02
Please tell the OP exactly how you did this, otherwise this answer is useless. – RolandiXor Sep 25 '12 at 16:09

I have this problem when installing 12.10. I've reinstalled Ubuntu with nomodeset parameters. It installs ok, but when boots for the first time I get the sema error "nouveau failed to idle channel 2" "nouveau failed to idle channel 3"

and so on

This doesn't strike me as an answer so much as an attempt to commiserate. The "answer" block is really intended for addressing an answer to the question rather than expanded commentary. I would suggest you delete this answer, and if you have this same problem, mark the star by the question to "favorite" it. This way you can keep an eye on it in the event it receives a valid answer. – Argusvision Oct 21 '12 at 21:33
