Has anyone succeeded installing or booting from the live CD where the motherboard is Asus K8N4-E?
According to a post in a german Ubuntu forum this board must boot with the option acpi=off due to a "timer problem" (my german is getting a bit rusty but I think that's what they ment).
I'v also seen that with the kernel version 2.6 you should use the option "pci=nommconfig" due to some other oddity with this board.
NB this is only for the K8N4-E not for other version of K8N4, and there are several versions.
nForce 4 boards are unfortunately known to be a bit troublesam also under Windows....
