Subject: Re: x2apic boot failure on recent sandy bridge system

Any update? The messages just seem to have stopped months ago. A fallback would be nice, I have been booting the kernel with noa2xpic for since kernel 3.2, and currently I am working with 3.6.2.

If needed I can try to attempt modifying the patch to include fallback, but I am probably not the best person to do it.
