Subject: [lkp] [i2c] faec3e0feb: WARNING: CPU: 31 PID: 1 at
drivers/i2c/i2c-core.c:1866 i2c_add_numbered_adapter+0x8d/0xa0
FYI, we noticed the following commit:
https://github.com/0day-ci/linux vadimp-mellanox-com/i2c-add-master-driver-for-mellanox-systems/20160828-225625
commit faec3e0febcaedb387cb244f2f493dc835351df3 ("i2c: add master driver for mellanox systems")
in testcase: will-it-scale
with following parameters:
test: page_fault1
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 64G memory
