Bug Description

Binary package hint: linux-generic

CONFIG_SERIAL_8250_RUNTIME_UARTS should be
increased to at least 32 in order to support multi port serial cards out of the
box. This will cover at least the situation, where two 8 port cards are used
simultaneously and there is still some room for internal ports or the other
card.

This bug report was created after initial discussion on the linux-serial
mailings list: http://www.spinics.net/lists/linux-serial/msg03020.html

Thanks Yegor.

I've reassigned this to the linux kernel package and added it as a tracking item to the config-review blueprint for Natty:
