Hello,

We ran automated tests on a recent commit from this kernel tree:

       Kernel repo: git://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git
            Commit: cc9917b40848 - mdio_bus: Fix init if CONFIG_RESET_CONTROLLER=n

The results of these automated tests are provided below.

    Overall result: FAILED (see details below)
             Merge: OK
           Compile: OK
             Tests: FAILED

All kernel binaries, config files, and logs are available for download here:

  https://artifacts.cki-project.org/pipelines/309848

One or more kernel tests failed:

    ppc64le:
     ❌ LTP
     ❌ xfstests: xfs

We hope that these logs can help you find the problem quickly. For the full
detail on our testing procedures, please scroll to the bottom of this message.

Please reply to this email if you have any questions about the tests that we
ran or if you have any suggestions on how to make future tests more effective.

Compile testing
---------------

We compiled the kernel for 3 architectures:

    aarch64:
      make options: -j30 INSTALL_MOD_STRIP=1 targz-pkg

    ppc64le:
      make options: -j30 INSTALL_MOD_STRIP=1 targz-pkg

    x86_64:
      make options: -j30 INSTALL_MOD_STRIP=1 targz-pkg

    💚 Pull requests are welcome for new tests or improvements to existing tests!

Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.

Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running are marked with ⏱. Reports for non-upstream kernels have
a Beaker recipe linked to next to each host.

I see a slew of syscalls failures here for LTP:

>       ❌ xfstests: xfs

Also generic/212 test failed for xfstests:

There are a few syslog failures, which does not seem to be related to
the kernel commit at all. The commit above seems to touch error handling
in a mdio bus which is used to configure network hardware. I would say
that this is connected to the rest of the unexplained failures on
ppc64le that seems to happen randomly.

I think this is different. Test is spam-ing serial console with:
 preadv203 (765613): drop_caches: 3

which leads to RCU stall:

Maybe we could temporarily lower printk level during this test.

Test also fails to release loop device and subsequent tests fail
because they try to use same one.
