Patrick,

You are running into a different problem than the ubd_user stuff.

Somehow your host kernel is returning an error on tty read.  It looks
like the error might be "Permission denied".  You can try changing
the sigio_user.c::tty_output() function to look like this at the end:

        ...
        else if(n == -EAGAIN) printk("No, enabling workaround\n");
        else printk(KERN_ERR "check_sigio : slave read failed, err = %d\n", -n);

(Basically change the last like from a panic to a printk and negate
the variable n.)

I see a problem in the file though it probably isn't causing any
problems right now.  Doesn't the variable got_sigio need to be marked
volatile?

-Ross
