This still fails on our slow VMs with debug kernel enabled (even tho they set KSFT_MACHINE_SLOW). The test runs for 15+ minutes without printing anything. That's pretty bad, humans running this tests will also have no idea what's going on. Maybe limit the runtime of the test as well as the iterations? To 1min? It takes <50sec on non-debug kernels in our CI. -- pw-bot: cr
