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
