[Madwifi-users] Compile errors

[John L. <ma...@fr...>]

Hello,

I've been using Madwifi for a while, and keeping it relatively current 
as I've been doing a fair bit of system configuration on my relatively 
new laptop.

Last week I installed Mandrake 10.1, and am trying to get ACPI suspend 
and hibernate to work correctly. Using a custom compiled version of 
2.6.8.1 with Mandrake patches. This is on an IBM Thinkpad T41, with the 
IBM Atheros a/b/g card.

With a CVS version of Madwifi from last Friday, I got everything mostly 
working. But when I resume, the Madwifi driver quits working after a 
small amount of traffic. This happens regardless of whether I unload the 
modules before suspending or not.

After a resume, I can reload the Madwifi modules, and re-associate with 
my AP. I can then see the network, ping sites on the Internet, connect 
to my IMAP server, everything. But as soon as I visit a web page or 
download a message, all connectivity appears to stop. At the same time, 
my USB mouse stops and so does my sound.

When I use "iwlist ath0 scanning", it doesn't find my access point. If I 
unload the madwifi modules, wait a little bit, then reload them, it 
sometimes starts working again--until I try to download anything. After 
a reboot, it works fine again. If I don't reload the madwifi modules 
after resuming, the USB and sound works fine, and they don't die.

I tried to update Madwifi to today's CVS, but am having trouble 
compiling it. I did a clean checkout, successfully applied the 
madwifi-2.6.8-mm_and_later-040927.patch, but when I compile it, I get 
lots of warnings like:

Are these expected, or what am I doing wrong?

Any suggestions for successfully suspending/resuming this driver? I'm 
currently bringing down the interface, then issuing: "modprobe -r 
ath_pci wlan_wep wlan ath_hal" before suspending.

Thanks for your help,
