Hmm, so did you apply the patch correctly?

Send me arch/x86/kernel/amd_nb.c after you've applied the patch.

Then, boot the kernel with my patch applied, send me full dmesg,
the .config used and do as root:

$ rdmsr --all 0xc0011021

and paste the output here please.

For that you'd need the msr-tools package and you'd need to modprobe
msr.ko if you haven't done so.

Thanks.
