I'm trying to get both PC-Card slots in a Gateway Solo 2300 to work under 3.2-RELEASE. dmesg sez that allocated IRQs are: 1 atkbd0 3 pcic 4 sio0 5 pcm0 6 fdc0 7 ppc0 12 psm0 14 wdc0 This leaves 9, 10, 11, and 15. pccardd can configure cards with 9, 10, and 15, when they're made available in /etc/pccard.conf. But after the insertion interrupt and configuration of the card, the card cannot successfully generate interrupts as it operates when configured with 9, 10, or 15. IRQ 11 works fine, though. I've searched the archives, and tried assigning the pcic to IRQs 9 and 10 by using the appropriate boot loader variable, and giving IRQ 3 to pccard.conf. But card insertion fails to generate an interrupt when I try to force the pcic to IRQs 9 or 10. I suspect that IRQs 9 and 10 may be used by other system devices that are not known to FreeBSD, but nevertheless there and conflicting with other uses of 9 and 10. Does anyone have experience with this particular laptop hardware? I may turn on pnp in the kernel (off so far), to see if this helps matters at all (not quite sure why it would...maybe the BIOS holds onto 9 and 10 for allocation by PNP devices only). Hmm. Maybe I should try moving the audio device off IRQ 5 (currently statically configured), to IRQ 9 or 10, and giving 5 to pccard.conf. Comments?
