Details:

I have tested the PPP with pppd and ping -f (flood). When I made reset the
device PPP started making LCP connection again. Some discards existed but
after receiving IP packet when upap was up the OS crashed (last message is
pppInput: ip).

Reason:
bug in ppp.c (3 times):
 pppControl[pd].netif.input(nb, &pppControl[pd].netif);

Solution:
there were the conditions necessary!
if (pppControl[pd].netif.input != NULL)
 pppControl[pd].netif.input(nb, &pppControl[pd].netif);
