Whatever you changed in the latest CVS tree has fixed my freezing problem. (I was getting the aforementioned error when it froze)
I was trying it with a zoom card and a linksys, and after a few seconds of high traffic, the system would get dropped. Only on Windows XP clients (I suspect earlier version of windows didn't ask for power saving facilities from the AP)
