I think this might be the cause:
By default linux has CONFIG_SERIAL_DETECT_IRQ turned off

>From the kernel docs:
This is considered unsafe; it is far better to configure the IRQ in
a boot script using the setserial command.

In potato the bootscript probes for ports using setserial, because
CONFIG_SERIAL_DETECT_IRQ is turned off, it doesn't find the correct IRQs but
uses the defaults. So if you have an internal modem the IRQs are wrong, you
have to manually set them. What is so very unsafe about this option? Would be
nice to have it enabled on the base image kernel.
