It does happen on two different hosts here running different GNU/Linux
systems (Trisquel and Debian) and different kernel versions (3.2 and
3.13). The one that recovers properly is Debian/3.13.

It is definitely something else. I can see what appears to be the
BootROM when pressing AUX:

Which disconnects properly indeed, but as soon as U-Boot starts, this

Note that the U-Boot version I am using is the one from:

Maybe someone else is experiencing the same issue with a GNU/Linux
