Btw, you can try below commands to reproduce the error on your local
host, they will download the necessary images and run QEMU:

       git clone git://git.kernel.org/pub/scm/linux/kernel/git/wfg/lkp-tests.git
       cd lkp-tests
       bin/lkp qemu -k KERNEL job-script  # job-script is attached in the original report email

Thanks,
