Hello

I'm following the intructions stated in this link for
touch screen support

http://sourceforge.net/mailarchive/message.php?msg_id=14681623

My problem is that modprobe snd-pxa2xx-ac97 will hand and not unload

        # modprobe snd-pxa2xx-ac97
        # modprobe ucb1x00-ts
        input: Touchscreen panel as /class/input/input0
        # modprobe evdev
        # rmmod evdev
        # rmmod ucb1x00-ts
        # rmmod snd-pxa2xx-ac97

The gumstix hangs when I execute rmmod snd-pxa2xx-ac97
I have to reboot the gumstix after this

That hang I think happens (or used to happen anyway) when you load the module, but there is no AC97 board connected.  I think there's some debugging options which can be turned on in the AC97 code when compiling, which might help track down where it's hanging during startup.
