Hello,

I am using a Lenovo Edge E530 and, with kernel 3.11.0-rc3, I had to
change to this parameter to the kernel boot:


GRUB_CMDLINE_LINUX="acpi_osi=\"!Windows 2012\""

I think it's pretty obvious that for the time being we need to
blacklist a ton of machines so they boot without this OSI. In fact, in
might make sense to simply remove the OSI completely for all machines
(for now).
