Hmmm. I'm too lazy to think. 5.4 is okay, 5.5-rc3 is broken... Let me
try 5.5-rc1 and then bisect. Unfortunately getting serial output is
tricky, too, since I need the USB for kexec...

If you know that there's known bug somewhere in 5.5-rc1, tell
me. Bisect can only locate one bug....

Best regards,
Pavel
