ubuntu_kvm_unit_tests panic-loop-extint fails on bionic s390x

[Luke Nowakowski-Krijger]

ubuntu_kvm_unit_tests panic-loop-extint fails on bionic s390x with kernel bionic/linux kernel 4.15.0-194.205 on s2lp3 and kernel02 in cycle 2022.09.19.

This looks like a new test case being added and was not tested in the last cycle.

Yes, this is because of the recent test suite update, with kvm-unit-test repo updated to d8a4f9e5 (ci: Update the list of tests that we run in the Fedora Cirrus-CI).

Thanks for the bug report! (Hint typo removed)

Test result on X-4.4 s390x is a bit different:
