Comment 15 for bug 1092102

I just ran into this on an Asrock board. Just installed a fresh 13.04 i386 and am running 3.8.0-25-generic.

I finally got 13.04 installed after many, many (of the usual) problems but the system is now booting by using the acpi=off kernel parameter. Without that, I get the modprobe errors. Hope this helps someone.
