Greeting,
FYI, we noticed the following commit (built with gcc-9):
commit: feb627e8d6f69c9a319fe279710959efb3eba873 ("KVM: x86: Forbid KVM_SET_CPUID{,2} after KVM_RUN")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: kernel-selftests
version: kernel-selftests-x86_64-99d09ee9-1_20211206
with following parameters:
group: kvm
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: 4 threads Intel(R) Xeon(R) CPU E3-1225 v5 @ 3.30GHz with 16G 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.

Hm, I'm pretty sure I've tested feb627e8d6f6 on both Intel and AMD and I
don't remember seeing this failure :-( . vmx_pmu_msrs_test test does
KVM_SET_CPUID after KVM_RUN and thus needs to be fixed too. Will send a
patch shortly.
