LUA loader: non UEFI boxes have weird ssh output

Just updated some boxes to 12-CURRENT r338057 and I face a very strange behaviour:

on non-UEFI booting boxes (older Fujitsu and Dell servers from 2008/2009, PCengine APU
2C4), logging in via ssh reveals broken output: even top does show nothing, the box is
stuck. Calling vi(1) on some files does alos freeze the terminal - no response, nothing.
On the PCengine, also applications like Asterisk do not work anymore - not output on the
console. The program is running, but stopped servicing. Only the serial console to some
of the "ssd-brain-dead" systems work, sshd is dead. This isn't the case on UEFI boxes
with the very same revision (r338057).

Is this a coincidence or is this/could this related to the switch to LUA loader?
