I don't have Juno R1 but I tried defconfig + CONFIG_PROVE_LOCKING and
it boots fine.
So if you disable CONFIG_PROVE_LOCKING(i.e. defconfig) boots fine ?
Are you using DTB from the mainline ?

OK, I use UEFI+GRUB but I don't think that should cause any issue.

Not that I am aware of. If you could send me the bootlog with defconfig
I can take a look and see if I get any clue.
