To reproduce:
git clone https://github.com/intel/lkp-tests.git cd lkp-tests sudo bin/lkp install job.yaml # job file is attached in this email bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test, # please remove ~/.lkp and /lkp dir to run from a clean state.
