[Madwifi-users] kernel oops in 2.6.2

[Matt F. <fi...@be...>]

Although here was a post about this, (specificly in fedora) I still have not 
been able to work out the cause.  In my case it is not caused by any patches 
on the kernel.  I have tried both the Debian source packages and the vanilla 
kernel source from kernel.org, with no luck.  My only thought is that it 
might have something to do with the debian utility to build kernel packages 
(make-kpkg) because after running that I need to run "make scripts" so it has 
the modpost utility.  Also I need to create a link (or copy) 
from .tmp_vmlinux1 to vmlinux because the module requires it (note there are 
two of those files, labeled 1 and 2).

Now for the strange part,  It works fine in 2.6.0 built exactly the same way.  
I have not tried 2.6.1 or 2.6.3.  When I first build it in 2.6.2 it works, 
but on next reboot it locks up and gives me the following errors.  What I did 
this time was load the modules before inserting the card, however it happens 
either way (hotplug does the insertion normally).
