Why does OpenBSD 4.7 i386 assign the pcic irq to 4 which is the
com0 isa port irq? Also, if there is a pcmcia card in a slot during
boot that card gets irq 3 which is the com1 isa port irq.
Later in the boot when com0 and com1 are detected dmesg shows:
com0: irq 4 already in use
com1: irq 3 already in use
irq 9, 10, 11, etc. are free and the bios is set correctly.
Any way to fix or get around this?
I need both com ports so I do not want to disable them.
(FreeBSD works perfect on same machine.)
