Hmmm... looks like you're right. Someone is stepping on ppp->tpkt in between
the time ppp_tty_push called ppp_async_encode and it was done with the packet.

ppp_tty_flush_output - seems unlikely. I don't know if its actually SMP
safe, but you're probably not getting flushes
ppp_async_release - could be... does this happen perchance when a connection
is being closed?
another ppp_tty_push - uh, I really hope ppp->tty_pushing isn't the only
thing serializing access here.. that doesn't look healthy to me.
