intel 3945 testing the drivers on slack

intel 3945 testing the drivers on slack

[Gallo Renato]

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

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...
