Sorry, I meant a clean build of the kvm selftests, not the kernel. The
kvm selftests makefile is a bit lacking and I've noticed that tests can
assert in random places if they aren't built from scratch - ensuring all
changed dependencies also get recompiled. Fixing up the makefile is on
my todo, but it wasn't very high on it, since 'make clean && make' is
fast enough.

I'm not sure either, and unfortunately I don't have the same hardware
as you to try and reproduce.

I checked the differences but nothing interesting stood out. I'm using a
defconfig config with a couple extra file system modules tacked on.
