Perhaps we're not setting up the fifo's correctly flor the uart
on the fifo?  What flavor/speed laptop is it?

When I connect the bitsy serial line to my desktop, con works as expected.
When I connect it to a laptop (with only one serial connector)
I loose characters of the boot loader output, sometimes I see its complete
prompt (boot>) somtimes only half of it, and the same for other output.

Any ideas where to start looking, what could be wrong?
I _think_ that in the past consolefs worked OK on the same laptop
(but maybe I changed kernels in the mean time).

Thanks,
Axel.

As far as I remember, we don't enable FIFOs by default, you have to
do that explicitly via a ctl message. That sometimes helps.
