Hi Gilbert,
Thanks for the custom version. I've integrated the changes into the
driver I'm working on.
For those wanting to test out the driver which is now fully up to date
with all change from NetBSD & OpenBSD - and has a few minor improvements
over them, grab it from:

http://www.clearchain.com/~benjsc/download/

File is: 20070125-wpi-freebsd.tar.gz

Full instructions on how to build / install the driver are in the README
in the tar file.

This should work both under -current and 6.2-Stable now.

Info about the driver and what's working/broken can be found at:

Cheers,
Benjamin

I have tried the new 20070125 version.
However, I did not manage to make work. At least, it compiles.
I have installed, both wpi_fw.ko and the if_wpi.ko, as the README said.
wpi_fw.ko lies in /boot/modules and if_wpi.ko in /boot/kernel.

When, I "kldload if_wpi", here is a small sample of /var/log/messages

Jan 27 10:30:39 vaio kernel: wpi0: <Intel(R) PRO/Wireless 3945ABG> mem 0xcc000000-0xcc000fff irq 18 at device 0.0 on pci6

Jan 27 10:32:19 vaio kernel: firmware_get: failed to load firmware image wpi_fw
Jan 27 10:32:19 vaio kernel: wpi0: could not load firmware image 'wpi_fw'

In kldstat, both modules are loaded.
Then, I have "kldunload if_wpi" (and if_wpi seems to be reload,
automatically, I don't know why). Same problem, it seems that wpi_fw
could not be load (found ?).

As a result, no AP is "associated".


After a fresh reboot, I have reinstall the custom 20070121 version of
mine, and all returns OK.
Another strange thing: when "kldload if_wpi" with 20070121 version, and
then kldstat, I don't see "wpi_ucode". It seems that wpi_ucode.ko does
not need to be loaded, in my case.
My wpi_ucode.ko lies in /boot/modules

After another fresh reboot, I first moved wpi_ucode.ko to another place.
When I "kldload if_wpi", I got the following message:

Jan 27 09:47:16 vaio kernel: wpi0: <Intel(R) PRO/Wireless 3945ABG> mem 0xcc000000-0xcc000fff irq 18 at device 0.0 on pci6

Jan 27 09:47:16 vaio kernel: wpi0: could not load firmware image 'wpi_ucode'

So, it seems that wpi_ucode.ko have to lied in my /boot/modules (the
place where I have also put if_wpi 20070121 version), even if it is not
loaded.
