The patch is queued up for 4.8. It's the usual chicken-and-egg problem... i=
f we
can't get enough users testing a patch early in a kernel cycle then it ends=
 up
having to wait for the next merge window.=20

I think that is part of the "few different issues" point. The -k =
microcode may
not be the only change required but AFAIK it is one part of the solution.=20

In other words if the patch and new ucode don't fix the problem that's still
useful information, and it doesn't mean the new ucode isn't worth running.=

Yep, that's a fair point. I was just trying to make sure we were collecting
good data. Thanks.
