In fact I've tried this and it did not help. At present I am changing my
whole architecture and refactoring plugins, working currently on "fast"
ones. So I don't have much time to play with heavyweight kernels like rar
or wpa. Anyway I am becoming more and more confident that the ASIC hangs
are actually a result of kernel bugs - e.g out of bounds writes or
something like that.
