Libertas Driver Locking Kernel

Wed May 21 12:21:35 EDT 2008

Greetings,

I'm using the libertas driver in 2.6.24 w/ firmware 8.73.7.p3 on a 8686 
chip over SDIO from embeddedworks.net.
I posted earlier about a problem with driver transfer sizes on the BF548 
board I'm using. I believe that is fixed (thanks again!).

When I load the driver and start sending traffic through the card it 
hard locks the kernel.  Below is the logging up to the point it dies. 
Usually just after a handful of packets.  I posted about this earlier 
but I think I've ruled the blackfin driver out at this point.
Can anyone make sense of exactly what is going on based on the logging?  
Thanks!
