No worries, no sorries needed for this (I know you fight to get things done).
I can't really say what is w/o Eric's patch.
As I replied to the BR #17772:
I added "lapic" boot-parameter as a result of a perf/NMI patch.
With both things "WorksForMe" I headed to other stuff in kernel development :-).
I was not aware that there was further discussion on the initial patch.

I am as always open for testing if there is a new patch around, just
let me know.
