Crash how? You must include a ddb trace when reporting kernel crashes. > It reveals after tests that the hostap mode is guilty.

I don't see this problem locally. Can you please try to narrow down the circumstances which trigger the problem a bit further? "device timeout" means that a frame could not be sent. Are you somehow creating conditions where the this could occur? is this problem triggered by particular client devices?
