So this has enough information to tell me that we have a kernel
problem there, good:

Unfortunately, not enough information to debug the problem, I'm
afraid. Questions to start debugging this would be:
a) is the problem deterministic?
b) is the problem present in v4.19.217 ?
c) what were the last -stable and -cip kernels that worked?
d) what device/module is causing the BUG?
Best regards,
Pavel

as the testing board are actually different is unclear.
The board and results can be seen here:
https://linux.kernelci.org/test/plan/id/61a587a0ab3b0079bd18f6d7/
the output log is here:
https://storage.kernelci.org/cip/linux-4.19.y-cip/v4.19.217-cip62/arm/omap2plus_defconfig/gcc-10/lab-collabora/baseline-panda.html
working board example log is here (works for 4.19.216-cip61 but using
a board on baylibre that could be different from the board on
collabora):
https://storage.kernelci.org/cip/linux-4.19.y-cip/v4.19.216-cip61/arm/omap2plus_defconfig/gcc-10/lab-baylibre/baseline-panda.html
looks like there is also a passed test on lab-baylibre for the panda
board with the same kernel:
https://storage.kernelci.org/cip/linux-4.19.y-cip/v4.19.217-cip62/arm/omap2plus_defconfig/gcc-10/lab-baylibre/baseline-panda.html
The job json file for replicate the job on a lava lab with panda board
can be found here:
https://lava.collabora.co.uk/scheduler/job/5113437/definition
> b) is the problem present in v4.19.217 ?

here is the diff with 4.19.217 stable

New regression, last pass: v4.19.216-cip61
This is the one that passed:

- About bisecting the kernel.
We are currently in the process of activating CIP to the list of
automated bisected kernel
for getting more information on this and future problems.
The following issue is the request to KernelCI for adding CIP to the
automated bisected kernel list.
