Comment 39 for bug 1866870

Yeah @Boris - it really seems to be an issue bound to the Merom/Penryn processor generation.

I asked Andreas to check through some kernels and qemu versions so that we maybe eventually can consider bisecting something. But that will take a bit of time.

Of course everyone able to spend some time can consider checking a few kernels of [1] as well (probably the easiest test to begin with).

Still if there is an x86-microarchitecture expert out there that say "ah penryn, I know we added/dropped ... " please speak up :-)
