I just installed CentOS 5.1 on a Dell Vostro 200 (Intel G33) which has a
Sunix PCI-Express (x1) 8-port RS-232 card installed. For me it looks
like only 4 ports are recognized, but I'm not sure if it's even working
with those 4.
>From 'dmesg' I see this:
...
Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled
ACPI: PCI Interrupt 0000:04:00.0[A] -> GSI 19 (level, low) -> IRQ 177
0000:04:00.0: ttyS0 at I/O 0xbf00 (irq = 177) is a 16550A

Couldn't register serial port 0000:04:00.0: -28

How can I get the other 4 enabled?
