buildhw-a64 01,02,20,21,22,23,24 are all lenovo emags that were running Fedora 39 happily
buildhw-a64-19,20 are thunderx2 were running Fedora 39 happily
bvmhost-a64-05 to bvmhost-a64-11 are all emags were running RHEL 8 (they were/are slated to be reinstalled with fedora and make into buildhw's)

After upgrading the Fedora 39 / buildhw's to 40 and rebooting they fail to boot with:

I was able to get one of them to pxe boot ok and start installer, so perhaps we just need to reinstall them. ;(
But would be nice to know if f40 will work on them at all.
