Comment (by davidkaroly):

 Yep, it was the the long descriptors.
 When starting Haiku with u-boot, TTBCR contains 0x8000...blabla, i.e. LPAE
 (aka EAE) is enabled.
 If I initialize TTBCR to zero, I start getting log messages from the
 kernel also on u-boot (and still 4th icon on the boot splash with
 TianoCore)
