[flashboot] Kernel panic when printing on serial console

Hello,

I have a Soekris Net-4501 running flasboot/OpenBSD-4.5

uname -a
OpenBSD fremen 4.5 SOEKRIS4501#0 i386

when I connect a NULL-modem cable to an USB serial port, I often
experience kernel panics.
They can be "solved" by typing 'c' on the KDB console. But I must be
physically present. Sometimes it hangs when I'm remote, if the cable is
plugged -- especially when the attached computer is shut down.

Have you experienced these kind of problem ? Is there a trick to not
suffer them ?

Regards,
