Description

Hello, similarly to #2373 I often get this failure on ppc64le, s390x, or aarch64 CentOS Stream 10 builders:

======================================================================
FAIL: psutil.tests.test_misc.TestCommonModule.test_debug
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/builddir/build/BUILD/psutil-release-5.9.8/psutil/tests/test_misc.py", line 580, in test_debug
    assert msg.startswith("psutil-debug"), msg
AssertionError
----------------------------------------------------------------------

This however sometimes happens and sometimes does not (possibly flaky or related to the exact machine the builder uses).

I can provide more details as requested or try to debug the problem if instructed. Unfortunately, I cannot use the machine interactively :(

I am retrying with @retry_on_failure()

I am retrying with @retry_on_failure()

Nah. One particular build either passes this test immediately or fails all the retrying attempts.

I attempted to fix this in aab8d09. Let me know how it goes.

[hroncok]

On it. First, I have verified that I can still reproduce the failures without aab8d09.

Now building with psutil/tests/test_misc.py changes from that commit.

Unfortunately no difference, still fails.
