[Ipw2100-devel] Problems with ipw2100-0.40

[Navin K. <ns...@an...>]

I know this is a little soon, but as soon as I got the latest driver I had 
problems removing the module (keyboard not responding).  As soon I had 
restarted I had a Kernel OOPS in ipw2100_tw or something like that as well as 
a Kernel Panic, so I couldn't get the log of the actual trace when my 
computer froze.  I also found this in my kernel logs:

Actually before, I was getting kernel oopses every single time I tried to use 
WEP in 0.40-pre2 and 0.40-pre1; however, these were in the hostap driver.  
This is probably due to my use of hostap cvs source(need the advanced WPA 
features for a class project with a prism card).  I've also still have had 
"Packet payload too large" errors on regular basis when using my school's 
wireless network.   

Here is the kernel oops I get from hostap:

Before 0.40, my transfers were reasonably okay.
