Bug Description

Issue found on 5.11.0-1005.5 Intel kernel.
Failed on amd64 node "spitfire", skipped on node "kili"

This is not a regression as it's testing the new branch (hirsute-WIP branch) with latest upstream code.

Seems to be fixed with: https://gitlab.com/kvm-unit-tests/kvm-unit-tests/-/commit/00073e2c03a4846fc58cb6cec5f573990e63b973

I didn't see this failures anymore with the test on B/F/J/K generic kernels.

Will put this on-hold until we have test results from various clouds.
