I have some suspicion that we have two problems, although I don't have
anything firm.

But my question to Manuel is that which cc do you use to make custom
kernel ? Is it egcs-1.1.2 ?
The GENERIC kernel of distribution is compiled by 2.95.3 as you know,
and if you are using egcs, there may be be slight chance ..

My PM4400 stops at

[ using 345616 bytes of netbsd ELF symbol table ]

even with serial console if the kernel is compiled by egcs-1.1.2.
(I need to double check to make sure. This observation may be
ghost,)

Oh no, too old secondary boot loader... I may be wrong.
