I ran 4.8-rc5 with these patches applied on a Skylake machine that shows
the various bts problems pretty quickly normally.

It ran a while and didn't hit any of them, but it did fall over with RCU
errors that are (probably) unrelated.

I'd have a better report but I'm having a lot of trouble getting kernel
oopses to appear on the serial console with this new install on the
skylake machine. It may not be totally systemd's fault but I am going to
blame it anyway.
