Arch Linux

Description:
After kernel update, when I try to shutdown my computer, it get stuck on kernel RIP messages, and when i try to suspend, it only block and goes to lock screen.
I did some research and saw some people with the same error, saying that probably was because the kernel could not turn off some device. In my case I think it is the wireless card.
In aditional after the same kernel update my discrete video card(optimus nvidia) isn't recognized anymore too.

Additional info:
* package version(s)
linux 3.12.2-1-ARCH

* config and/or log files etc.
On attachment my full kernel log mesage. I think the error mesages is on the last 100 lines.

Steps to reproduce:
On any way possible to shutdown(dbus send, shutdown, systemctl, halt)
When I try to suspend the system(some times the kernel chashes and some times only get lock screen)

p.s.: Just when I was writing this post, my kernel crashed and I had to shutdown manually when i tryied to suspend to get the kernel mesages.
