I'm using a Netgear FA120 USB ethernet adapter with the axe driver, and my kernel panics with a page fault in usb_transfer_complete every time I attempt to bring the interface down. This means I can't reboot without a panic. It looks like this code might address my problem. I've never tested a patch in this manner before though. I assume there's some utility like mergemaster to merge this into my existing code. If somebody can tell me how to merge in these changes I'll try them out this week and let you know how it goes.
