The most recent RHEL 9.5 updates updated the kernel:

  kernel (5.14.0-447.el9 -> 5.14.0-452.el9)
  kernel-core (5.14.0-447.el9 -> 5.14.0-452.el9)
  kernel-modules (5.14.0-447.el9 -> 5.14.0-452.el9)

but there's no corresponding kmod-kvdo rebuild in place, so vdo tests fail with

Error creating volume: Process reported exit code 3: modprobe: FATAL: Module kvdo not found in directory /lib/modules/5.14.0-452.el9.x86_64

This is well understood, we had similar bugs like https://bugzilla.redhat.com/show_bug.cgi?id=2180074 and https://bugzilla.redhat.com/show_bug.cgi?id=2172911 . The latter was meant to be a "forever open" placeholder bug, but I didn't find one on Jira.

We need to track and mark these as "known broken by OS" bugs in our CI, so filing this as a reference.
