I can't duplicate this. Can you check you don't have

config SERIAL_8250_DETECT_IRQ
bool "Autodetect IRQ on standard ports (unsafe)"
depends on SERIAL_8250_EXTENDED
help
Say Y here if you want the kernel to try to guess which IRQ
to use for your serial port.

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

If unsure, say N.
