It appears we are getting an opcode error when attempting to boot Centos 9-stream utilizing the EFI artifacts from Ubuntu. Technically this should work, however further aftifacts in the boot chain may be signed with other key credentials that Ubuntu's grub does not know about, because the chain of trust is MSFT -> Vendor shim (slow change rate) -> Vendor GRUB -> Kernel Where vendor differences should never work, is if Secure Boot is enforcing. Exception on launch: X64 Exception Type - 06(#UD - Invalid Opcode) CPU Apic ID - 00000000 !!!! A similar Debian bug is open for a very similar issue: https://groups.google.com/g/linux.debian.bugs.dist/c/BOiLLeROrmo However, no additional comments or information have been in follow up to that reported issue. So in the mean time, we're going to try and do what those smarter than I recommend, use the vendor's binaries for their distribution. There is one further, potentially far more depressing possibility, that centos9's kernel doesn't support the type of hardware we're getting. This is suggested by the precise opcode error, UD, https://xem.github.io/minix86/manual/intel-x86-and-64-manual-vol3/o_fe12b1e2a880e0ce-212.html But again, easiest possibility first.
