I'm trying to make the bcm43xx driver out of the 2.6.20-rc1-mm1 kernel work on an HPC nx6325, with no luck, so far, although I'm using a firmware that has been reported to work with these boxes (http://gentoo-wiki.com/HARDWARE_Gentoo_on_HP_Compaq_nx6325#Onboard_Wireless_.28802.11.29). The driver loads and seems to operate the hardware to some extent, but there seems to be a problem with interrupts. Namely, the chip doesn't seem to generate any. Raphael J.

There is a fix in the pipeline, but it has not propagated through the system. You should apply the work_struct2 patch attached. If your computer has a switch to kill the RF, you may also wish to apply the radio_hwenable patch, which should cause the radio LED to be turned on. The selection of eth2 rather than eth1 is probably due to the rules in /etc/udev/rules.d/30-net_persistent_names.rules.
Ah, I'll check that, thanks. It used to be eth1, though, and I haven't changed the udev configuration myself.
When I boot a softmac version, my bcm43xx device is wlan0, but when I boot the d80211 version, it is eth1. I have a second bcm43xx card, which becomes eth2 under softmac.
Thanks for the patch. In the meantime I've browsed the bcm43xx-dev archives and found some other interesting patches for me to try. ;-) Greetings, Rafael -- If you don't have the time to read, you don't have the time or the tools to write. - Stephen King
