Alas, I've tried both on a clean linux-next (next-20250312), and after doing an allmodconfig build (and make mrproper), and am still unable to reproduce this here. I also dug up the old 5.10-based version we saw something similar on, and wasn't able to reproduce it there, either. (That had been built with clang, but using clang on upstream doesn't seem to reproduce it either.) I'll continue to play around with different setups, but none of the obvious things seem to work. Worst-case, I don't think it'd be a _problem_ to make EFI + AMD_MEM_ENCRYPT the default for the x86_64/qemu KUnit configuration. -- David
