Subject: [cpuidle,intel_idle] 32d4fd5751:
WARNING:at_kernel/rcu/tree.c:#rcu_eqs_exit
Greeting,
FYI, we noticed the following commit (built with gcc-11):
commit: 32d4fd5751eadbe1823a37eb38df85ec5c8e6207 ("cpuidle,intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: kernel-selftests
version: kernel-selftests-x86_64-cef46213-1_20220609
with following parameters:
group: resctrl
ucode: 0x500320a
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: 88 threads 2 sockets Intel(R) Xeon(R) Gold 6238M CPU @ 2.10GHz with 128G memory
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
If you fix the issue, kindly add following tag

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.
