Comment 28 for bug 2019856

The autopkgtests failures in lunar seem to be a kernel issue during the initialization of the virtio rng driver, when the mutex for (generic/core) hw rng is acquired (apparently something else is holding it indefinitely, thus the blocked task warnings show up, and it seems the VM doesn't proceed to the point of being detected, and the test fails/times out).

I haven't seen related commits listed in the later linux package changelogs for lunar (this is with 6.2.0-25-generic), nor could reproduce this in a LXD VM with the same version (it uses a virtio rng device too).

Let's try again when another openstack image for lunar is available (current/failing is 2023-07-17).
