Thanks for bringing this up.  The status in the HTML log file is
a very coarse one, in this case the board booted "fine" since it
reached a login prompt.  The issue was detected later when
checking for errors in the kernel log.

But yes you're right, the issue is also impacting imx53-qsrb
indeed.  I didn't spot that because it was only reported as a
regression on staging.kernelci.org, whereas imx53-qsrb is in the
Pengutronix lab which is not sending results there at the moment.

The failures can be found on the production web dashboard though,
but not as regressions:

beaglebone-black:

  https://kernelci.org/test/case/id/5f6c7f1ab7c8c5472cbf9de9/

imx53-qsrb:

  https://kernelci.org/test/case/id/5f6c7ea6f89a9d0f4dbf9ddf/


I need to investigate why that is the case, knowing that the
regression was detected correctly on staging which is the
development KernelCI instance:

  https://staging.kernelci.org/test/plan/id/5f6bea67f724eb1b34dce581/


Thanks,
Guillaume
