Reports aren't automatically sent to the public while we're trialing new bisection features on kernelci.org, however this one looks valid. The bisection started with next-20201118 but the errors are still present in next-20201119. Details for this regression: https://kernelci.org/test/case/id/5fb6196bfd0127fd68d8d902/ The first error is: [ 14.757489] Internal error: synchronous external abort: 96000210 [#1] PREEMPT SMP Full log: https://storage.kernelci.org/next/master/next-20201119/arm64/defconfig/gcc-8/lab-baylibre/baseline-meson-gxbb-p200.html#L410 Some other platforms are failing to boot starting with next-20201118 but it's unclear whether that's due to the same issue. They might lead to a successful bisection which would help clarify this. All the baseline test results can be found here: https://kernelci.org/test/job/next/branch/master/kernel/next-20201119/plan/baseline/ Hope this helps. Pleas let us know if you need some help to reproduce the issue or try a fix.
