I also volunteer to test this new driver. I often have problems with the
current driver provided by Realtek. It seems the connexion is quite
unstable and I often get kernel panic like this one:

rtl8192se_rx_normal+0x143/0x400

kernel panic not syncing fatal exception in interrupt PID: 0, comm:

call trace:

I already asked realtek support about this but I didn't get a lot of
help from them. So, I would be interested to see if the new driver you
talked about perfoms better.

Thanks in advance,
