Wait, why do you want these for the 6.6.y tree if you haven't even tested to see if they are required or work there? Why not just move to 6.12.y instead as you know that works.
The original problem was reported by me on 6.6.y. I tested the patch provided by Borislav on 6.6.y. As mentioned, a small change is required to make it compile, but this is a nonfunctional change in the tested code path and so didn't influence test results. I can therefore say with certainty that the fix is required on 6.6.y .
In these discussions, I requested Borislav if the patch could also be submitted for 6.6.y, and made him aware that variable 'bsp_cpuid_1_eax' used in the patch does not yet exist in that branch. He replied [1]:
"That's fine - stable folks usually know what to pick up. If not, I'll provide backports."
I cannot currently move to 6.12 for these systems, this has other consequences and testing efforts.
Thanks, Thomas
