        Commit: c2fb28a4b6e4 - Linux 5.7.9-rc1

The results of these automated tests are provided below.

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

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

 💥 Boot test

Hi,

we started observing boot panics with 5.7 on s390x yesterday:

I only released one of the reports to not spam too much but the panics are still happening with the most recent code.

These panics are NOT present on the current mainline. All other arches are OK.

Given the call trace, I'm guessing it is something related to

Compile testing

We compiled the kernel for 4 architectures:

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

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

s390x:
  make options: -j30 INSTALL_MOD_STRIP=1 targz-pkg

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

Aborted tests

Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report.

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 yet are marked with ⏱.
