I have a DLink DWL650 wireless card, on a P90, and I'm desesperately trying
to get it working on a FreeBSD 4.7 system.
I wanted to setup it on a FreeBSD 4.7, but the box freezes after printing:
Mounting root from ufs:/dev/md0c
So I looked on the net, and added the following lines to my
/boot/loader.conf file:
hw.pcic.irq="0"
hw.pcic.intr_path="1"
Now, FreeBSD boots very well, all others network cards are working properly
(1 NE2000 ISA card and 1 Realtek PCI card), but I always get the following
line
just after pccardd setups the card:
wi0: watchdog timeout.
I looked on the web and in various man pages, and found a lot of references
(solutions?) to the following variables (to define in /boot/loader.conf):
hw.pcic.ignore_function_1: 0 to enabled function 1 - 1 to disable function 1
hw.pcic.init_routing: 1 to force to route via PCI interrupt - 0 default
hw.pcic.intr_path: 1 to route via ISA - 2 to route via PCI
hw.pcic.irq: override the IRQ to use for ISA interrupt routing - 0 to use
polling mode
hw.pcic.ignore_pci: no documentation found about this one, but seems to
fully disable PCI probing
machdep.pccard.pcic_irq: override the IRQ normally assigned to a PCCard
controler - 0 to use polling mode.
Finally, some IRQs settings can also be applied through pccardd -i, or in
/etc/pccard.conf.
I think my problem is due to an IRQ conflict.
Theoretically, from what I see with various tools (by looking at /proc
informations using Linux, ...)
it seems that IRQs 3, 5 and 12 are free on the box.
My questions are:
- How does all those PCI/ISA/IRQ settings interact all together ?
- How to setup those to have a properly working wireless card?
- Else,is it possible to indicate me the appropriated mailing list /person
where I can get an answer?
With an /boot/loader.conf as following:
userconfig_script_load="YES"
hw.pcic.intr_path="1"
hw.pcic.irq="0"
and the line pccardd_flags=" -i 12" in /etc/rc.conf,
Here's what I get during the boot (dmesg output):

Don't forget I must conserve the following settings to boot properly:
(except if you have another solution...;)
hw.pcic.irq="0"
hw.pcic.intr_path="1"
