What serial driver initialization messages do you get from dmesg? Is the "MANY_PORTS" flag present in the list of enabled options? Which distribution and rev level are you using?
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).

BTW, this is with 2.4.19 (kernel shipped with distro).... I'm willing to test any patches / rebuild kernel to get this working.....

It seems devfsd has an annoying "feature". I bought a PCI card to get a couple (2) more serial ports. The kernel doesn't seem to set up the serial ports at boot, so devfs never creates an entry. However, post boot, since there is no entries, I cannot configure the serial ports with setserial. So basically devfsd = no PCI based serial add on?

I hoped after "setting up" the serial ports with setserial some magic would happen and they would apear in /dev/tts... but I was wrong.
gets me working serial ports... but it's not in /dev... :O
Am I just screwed?
If so, what would be a good add on PCI based solution for more serial ports that WORKS with devfsd? (I don't want to disable devfs as this opens up a different set of problems)
Thanks for any replay!
