If you build the kernel with CONFIG_DEBUG_INFO_BTF, there is a 50% chance that you will see "Failed verification: in-kernel BTF is malformed" during boot. There was also a hang, reported by one of our kernel team members, that we tracked down to the same issue, but unfortunately I cannot find any details about it right now.
