>From 8250_pci.c, you have :
* Probe one serial board. Unfortunately, there is no rhyme nor reason
* to the arrangement of serial ports on a PCI card.
It seems that your board is reporting the parameters in such an order
that when looking for a port based on the IRQ, I/O port, ... the matching
one has id 14...
You could see this more clearly by setting SERIAL_DEBUG_PCI
at line 1549 to activate the code :
printk("Setup PCI port: port %x, irq %d, type %d\n",
serial_req.port, serial_req.irq, serial_req.io_type);
that would report to you the order in which ports are found on
