This might be your problem.

Couldn't set tty to PPP discipline: Invalid argument
Symptom: the following messages appear before connection is established:

Serial connection established.
Couldn't set tty to PPP discipline: Invalid argument
Hangup (SIGHUP)

Diagnosis: pppd has failed to change the pty over to run it in PPP mode. This may be because you have no ppp_async module built for your kernel. Most kernels are built with this already, but if you have customised your kernel you may not have built it.

Solution: rebuild your kernel with CONFIG_PPP_ASYNC set. While you are at it, you should set CONFIG_PPP as well, and both should be set to "m" so that they are built as modules. We've found they don't work compiled statically.
