Subject: [x86/acpi] 04c197c080: BUG: unable to handle kernel paging
request at 0000003000000010
FYI, we noticed the following commit:
https://github.com/0day-ci/linux Dou-Liyang/Fix-the-local-APIC-id-validation-in-case-of-0xff/20161008-154907
commit 04c197c080f2ed7a022f79701455c6837f4b9573 ("x86/acpi: Fix the local APIC id validation in case of 0xff")
in testcase: will-it-scale
with following parameters:
test: unlink2
cpufreq_governor: performance
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.
on test machine: 72 threads Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz with 128G memory
