Therefore, I haven't tested your latest patch yet. I wanted to determine whether this problem would occur often. If you like I can go ahead and test the patch anyhow. I am currently testing mm5 + the pcmcia patch and the hostap patch. I am looking into a crashing (system lockup) bug that is triggered by removing my Linksys USB 10/100 Ethernet adapter. This problem is 100% repeatable. I am working on setting up a remote debugging configuration. Would you like me to go ahead and test your latest patch? Thanks, Miles
