FYI, we noticed the following commit:

commit: 935356cecda851d94381e1c6fea9dec443f908fe ("x86/apic: Initialize interrupt mode after timer init")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git x86/apic

in testcase: will-it-scale
with following parameters:

	nr_task: 100%
	mode: process
	test: open2
	cpufreq_governor: performance

test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale


on test machine: 256 threads Phi with 96G memory
