Greeting, FYI, we noticed the following commit (built with gcc-9): commit: 159d8c274fd92438ca6d7068d7a5eeda157227f4 ("ACPI: Pass the same capabilities to the _OSC regardless of the query flag") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: kernel-selftests version: kernel-selftests-x86_64-c8c9111a-1_20210929 with following parameters: group: firmware ucode: 0xe2 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) i7-6770HQ CPU @ 2.60GHz with 32G memory caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace): If you fix the issue, kindly add following tag Reported-by: kernel test robot <oliver.sang(a)intel.com&gt; TAP version 13 1..1 #
