2011-05-26 // Fedora 15 Lovelock on Gigabyte GA-MA78GM-UD2H
One of my older desktops is based on a Gigabyte GA-MA78GM-UD2H mainboard (AMD 780G North Bridge, AMD SB700 South Bridge). Booting Fedora 15 Lovelock on this machine did not work. It took ~4h [sic!] to boot because the USB hardware detection was freaking out (you will only see a gray background with a white, blinking cursor for several hours and you have to wait when looking at ehci_hcd
messages).
However, the solution is simple: make sure you got the latest mainboard BIOS (version F9B 2010/07/08 as I'm writing this) which fixes several bugs Fedora seems to stumble upon. Everything works perfect then.
Update: Don't halloo till you're out of the wood! After a few days of usage, there are still “it hangs” problems during boot and poor performance at all. E.g. you have to (un)plug a USB device when the OS does not do anything. In short: it sucks. But it does not matter. Time to get a new machine anyway.
