Recently we use Version 80 of Avocado to run kretprobe.py in Rhel8.4, and it still shows "FAIL: insmod kretprobe_example.ko failed": 《SOL-Log》 《Avocado Test Log》 Since in the past we could use Version 80 of Avocado to run kretprobe.py in Rhel8.2, and the result was PASS, please check if it is Rhel8.4's limit to run kretprobe.py.

After we use Version 93 of Avocado to re-test it, it still shows "FAIL: insmod kretprobe_example.ko failed". 《SOL-Log》 《Avocado Test Log》 |

@disgoel is this still an issue on the recent run? |
