Subject: [lkp-robot] [x86] ed3ce2a917: BUG:unable_to_handle_kernel
FYI, we noticed the following commit:
commit: ed3ce2a9172457ef7dbaa9f964e63dfde2bdcb5f ("x86: Optimize clear_page()")
url: https://github.com/0day-ci/linux/commits/Borislav-Petkov/x86-Optimize-clear_page/20170215-193441
in testcase: will-it-scale
with following parameters:
test: poll2
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: 8 threads Ivy Bridge with 16G memory
