https://bbs.archlinux.org – linux-3.3.1-1 made it to core about a day ago. Now I can get to the login screen without noefi and no patches. Still no keyboard functionality though.The strangest thing is that the keyboard works with the LiveCD (ArchBoot in EFI mode). What's the difference?I was able to boot with the lvds_channels patch but no keyboard.Judging from the large number of uhci_hcd (USB Universal Host Controller Interface driver) and ehci_hcd error I get at boot, this issue may affect all USB devices (the built-in mac keyboard is a usb device).One difference I noticed between the live cd and the installed sy (HowTos)
