DDB doesn't work (the INSTALL kernel is also compiled with options DDB),
but I could narrow it down to "machdep.c". If I set 
COPTS.machdep.c+=-O2 in sys/conf/
the kernel boots successfully.

Unfortunately, that's not the area where I would understand much of the
code and do any further debugging, but if there's anything else which I
can test, I'd be happy to do that.

Best regards,
