I have a Dell Latitude CP (M233XT) that I'm trying to get working reliably with a modem and an ethernet card. Given the following output from dmesg (hand copied, so there may be typos): . . pcic0: <TI PCI-1131 PCI-CardBus Bridge> rev 0x01 int a irq 11 on pcic0.3.0 pcic1: <TI PCI-1131 PCI-CardBus Bridge> rev 0x01 int b irq 11 on pcic0.3.1 . . . PC-Card VLSI 82C146 (5 mem & 2 I/O windows) pcic: controller irq 10 . . . My understanding is that the pcic controller uses an irq to signal the kernel (and pccardd that a card has been inserted or removed. Also, I found that the irq used by the pcic controller can be specified in /boot/loader.conf with the line ``machdep.pccard.pcic_irq="X"'' where ``X'' is the desired irq, or ``0'' to disable the irq and put the pcic controller in polled mode. So that all makes sense, but what is the purpose of the irq 11 used above by pcic0 and pcic1? Can I use that irq for PC cards or is it used for something by the pcic controller? Thank you.
