kernel hangs immediately after loading

Hi,

I just cross-built a kernel (-current sources about a week old) and tried to
boot this from a floppy. This is what I see with the serial console:

  >> NetBSD/bebox BOOT, Revision 1.5
  >> (heinz <at> silence.homedns.org, Sun Mar 21 18:15:11 MET 2004)
  >> Memory: 98304 k

  Boot: Loading in()
  2853792+169964 [86480+72406]=0x3092e8
  start=0x3100

No more output.

Inserting printf() in stand/boot.c shows that the loader must reach
line 204 (run(..)) where the kernel starts.

Does anyone else see the same behaviour?

ciao
