My boot messages say this:
Serial driver version 5.05c (2001-07-08) with HUB-6 MANY_PORTS MULTIPORT
SHARE_IRQ SERIAL_PCI ISAPNP enabled
ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS01 at 0x02f8 (irq = 3) is a 16550A
It only sets up my built-into-motherboard serial ports. The add on card
gets ignored.
I would have thought with SERIAL_PCI enabled I would have no problem.
But it doesn't seem to be so.
doing the quick/dirty setserial stuff with my own mknod's work. but it's
a big "messy". I'd at least like to get this fixed so next kernel
version I don't need to do a quick hack todo something as simple as
getting a serial port working.
I can post my entire dmesg if needed allong with my complete /proc/pci.
I'm also willing to play with patches. (if this is already fixed in a
later kernel than 2.4.19 I'd be willing to give it a go).
