Tested separateöy and together, with the previous debug patch applied.
debug+patch1 caused no visible change cmpared to just debug - same crash before starting init as with plain debug patch.
debug+patch2 caused a change - now instead of hang before starting init, it hangs after starting init as with no patch applied.
debug+patch1+patch2: works, dmesg attached:
