intel 3945 testing the drivers on slack

got this expencive new acer and trying to manage it with slackware. My first try with the kernel 2.6.20.4 was with the ipw3945.ko driver and its daemon

(ipw3945# ls
ipw3945-1.2.0/ ipw3945-1.2.0.tgz ipw3945-ucode-1.14.2.tgz ipw3945d-1.7.22/ ipw3945d-1.7.22.tgz
)

but since sometimes it gives me this trouble:

ipw3945: Microcode SW error detected. Restarting.
ipw3945: request scan called when driver not ready.
ipw3945: Error sending ADD_STA: time out after 500ms.

on the dmesg and disconnects losing the wireless extentions I decided to try the new kernel 2.6.20.6 with the drivers
iwlwifi-0.0.11/ iwlwifi-0.0.11.tgz iwlwifi-ucode-2.14.1/ iwlwifi-ucode-2.14.1.tgz mac80211-6.0.0/ mac80211-6.0.0.tgz

but got troubles compiling since after the patching phase it gives me

CC drivers/net/wireless/mac80211/iwlwifi/base.o
drivers/net/wireless/mac80211/iwlwifi/base.c: In function `ipw_rate_scale_rate_init':

during the compile phase....

since I think I am missing something I would really appreciate if you could find the time to guide my ideas on the right path (it is the first time I face this kind of new hw).

thanks in advance for the advices....

It sounds like there is a mismatch between the iwlwifi version and mac80211 version you are using? Dunno.

I'll leave it to the iwlwifi guys to answer more...
