Comment 12 for bug 721576

I only run ubuntu in uefi mode (well gpt partition etc) without the noefi the computer crashes on reboot halt and suspend.
I also had trouble with my wireless card without noefi ie the card would say disabled by hardware switch if i did not try to boot from lan in the boot order. also my bluetooth started working. either linux has a new and buggy efi support in the kernel or my hardware has a relly buggy uefi implementation.

Grub2 and all of that is in uefi mode so i relly dont know what the noefi cmd does to the kernel. Im guessing that the kernel just skips the uefi tables and that uefi has the old tables for backward combability
