The pcic works in polled mode and i have finally discovered it works in interrupt mode with the following config device pcic0 at isa? irq 9 port 0x3e0 iomem 0xd4000 However under windows and freebsd 3.3+PAO it worked on IRQ 11 Under 4.0 IRQ 11 appears as used by the Neomagic Sound Card. It is not used by freebsd on this IRQ since the config is: device pcm0 at isa? irq 5 drq 0 flags 0x11 I have even tried to use the visual config screen to put IRQ to 11 (which did not work) and hot reboot to IRQ 9. Then the pcic still did NOT work. I had to cold reboot to get it to work again. Similarly the USB controller gets hooked on IRQ 10 (as in windows) and does NOT work (it was the same on freebsd 3.3). No insertion or removal events are reported. On another machine i have this works OK. Finally the iicbus and smbus stuff don't work either. I think they both share IRQ10 and this causes problem. These are PCI devices and i cannot do anything to change the IRQ settings. -- Michel Talon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
