]]>For future n00bs:
I have a UEFI motherboard and my graphical output is through a GTX 780 Ti. The motherboard is a Sabertooth X79, and has no standard VGA output. When I tried to boot an archiso (from a usb stick) in UEFI mode, it would hang at 'triggering uevents', as described above. It would boot normally is BIOS/Legacy mode.
By pressing 'e' at the bootloader menu, I had the opportunity for the input that I was looking for. There was only a single line, so I stuck the following in at the beginning:
linux /boot/vmlinux-linux root=UUID=978e3e81-8048-4ae1-8a06-aa727458e8ff nomodeset nouveau.modeset=0
Your parameters (nomodeset, nouveau.modeset=0) will vary by hardware. Through my reading, it seems to be tied to the graphics card.
You can find the proper parameters here.
]]>Thanks for your patience; I'm still learning.
]]>Could you please tell me how and where did you set that. I have the same problem, and don't know where these parameters are.

https://wiki.archlinux.org/index.php/Kernel_parameters
I solved using the "nomodeset" option as boot parameter, but what does mean?
That's not a solution (people have been using that as a "solution" for a while, instead of reporting bugs, and therefore radeon still has this problem. Yay). Current versions of the radeon driver will not work this way.

Thank you.
]]>Is this option change something in the install process and/or the installation result respect without using it?
]]>radeon still supports both modes - however, the modesetting mode fails for your specific card. This is a bug that should be reported to the radeon people - however, the latest Arch live image uses Linux 3.5.5, and our latest version is 3.6.3 - this means that after installation, this bug may already be fixed (at least you should test if it is).
]]>Using the option loglevel=7, I get the boot stops at the same line when I try to boot from the USB Kubuntu 12.10, it's the following:
[3.732195] radeon 0000:01:00.0 > radeon : using MSI
I'm facing the same problem...
]]>To address this, I'd be surprised if it were USB specific. Have you looked through the various previous threads on boot hangs at that line? There are quite a few of them, they should give some ideas.
