Comment 26 for bug 1900668

One node is already tweaked a bit, as I fixed doing SecureBoot deployments on it.
And other one has centos deployed to debug another bug.
But I can revert back to "stock grub" non-secureboot and see if I can reproduce things.

Maybe we need to compare fw / bios versions too?

Or for example any other networking details / firewall / routers that might be different on my lucky two nodes.
