Yes, I could be more specific. When I said "the only way
I can run..."  I mean the official images don't even boot.

The errors differ but they were related to xhci I think.  I'll make
some test with the u-boot in ports, but after reading your experience
with other rev 1.4 boards I wonder if this could be related with
the eeprom firmware, if this is even possible.

The xhci|pci dma bug on the 2711B0 is well known, and if it is not
dealt with, you know the hell that is coming specially if your root
file system is in a usb device. Also ufs+su+j seems to have a funny
way to recover states with zeroed files, but that's another
discussion.

Just take it as a report... to the list.
