Subject: [arch/x86] 9bfaa248c8: WARNING: CPU: 8 PID: 48 at
arch/x86/events/intel/uncore.c:1151 uncore_change_context+0xbf/0x13a
FYI, we noticed the following commit:
https://github.com/0day-ci/linux Prarit-Bhargava/arch-x86-Remove-second-call-to-topology_update_package_map/20161012-231511
commit 9bfaa248c817a9f6734d5daee3b33c25d8a73f0d ("arch/x86: Remove second call to topology_update_package_map()")
in testcase: will-it-scale
with following parameters:
test: pthread_mutex1
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: 32 threads Intel(R) Xeon(R) CPU E5-2680 0 @ 2.70GHz with 32G memory
