Actually, looking at the "top" output, shows that pppd is stuck in "select" state, so getting a kernel stack trace of that wouldn't be helpful. I don't know how ppp works in the kernel, but am trying to track down problems where it wedges our serial line and we have to kill pppd with SIGKILL in order for it to notice (SIGTERM and SIGHUP don't seem to produce any effect).
