Hi:

I have a Soekris net4801 which runs from a compact flash disk. It boots
to the serial console. I've set everything to 9600 baud, 8 bit words, no
parity, 1 stop bit.

When left unattended, it boots normally.

If I try to enter anything at the boot> prompt, I see one character and
then it hangs completely. Only a hard reset fixes it:

Obviously, this is bad because it means I won't be able to pass any
kernel parameters should that become necessary.

If I do nothing or hit enter, the system boots normally -- no greek, no
garbage -- which would suggest it's not a baud rate problem.

Has anybody encountered this before?

Thanks,
