[ghost]

i.e. once https://github.com/open-power/skiboot/issues/163 is fixed

[harihare]

https://github.com/open-power/skiboot/issues/163 the issue is fixed.

[harihare@harihare op-test]$ grep -nir "xive" * Binary file test_binaries/oskernels.tar matches Binary file testcases/pycache/KernelLog.cpython-38.pyc matches testcases/KernelLog.py:98: # The below xive message should go away when https://github.com/open-power/skiboot/issues/171 is resolved testcases/KernelLog.py:99: "xive: Interrupt.*type mismatch, Linux says Level, FW says Edge",

Remove line 99 and send the patch.
