Dear friends,
I use to run some experiments to test each new kernel version, and
noticed that commit 2a51fe083eba7f99cbda72f5ef90cdf2f4df882c have
disrupted my tests. When I run a qemu/kvm guest with "-no-acpi", or
boot with "noacpi" or "acpi=off", the guest cannot boot, but stays
apparently in a infinite loop, usin 100% of cpu.
I reversed the patch, my experiments run smoothly again.
Thank you, very much
Edivaldo de Araújo Pereira
P.S.: resent after instruction from the friendly email-bot of Greg
Kroah-Hartman.

Odd. Care to cc: all of the people involved in that patch as well?
Also, is this still an issue with Linus's tree?
thanks,
