Subject: [selftests]  e71b7f1f44: kernel-selftests.net.fcnal-test.sh.fail



Greeting,

FYI, we noticed the following commit (built with gcc-11):

commit: e71b7f1f44d3d88c677769c85ef0171caf9fc89f ("selftests: add ping test with ping_group_range tuned")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: kernel-selftests
version: kernel-selftests-x86_64-cebf67a3-1_20220613
with following parameters:

	group: net
	test: fcnal-test.sh
	atomic_test: ipv6_ping
	ucode: 0xec

test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt


on test machine: 8 threads Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz with 28G memory

caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):

To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.
