Greeting,

FYI, we noticed the following commit (built with gcc-9):

commit: bfcc1e67ff1e4aa8bfe2ca57f99390fc284c799d ("PM: sleep: Do not assume that "mem" is always present")

version: kernel-selftests-x86_64-c8c9111a-1_20210929
with following parameters:

	group: group-00
	ucode: 0x11

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: 288 threads 2 sockets Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with 80G memory

# selftests: breakpoints: step_after_suspend_test
# TAP version 13
# Bail out! Failed to enter Suspend state
# # Totals: pass:0 fail:0 xfail:0 xpass:0 skip:0 error:0
not ok 1 selftests: breakpoints: step_after_suspend_test # exit=1



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.
