Hi! Sorry for topposting, but I don't know if this has got something to do with your changes: I am trying to rebuild my -CURRENT system now for some days and keep receiving panic messages from ng_ppoe like this panic NG_MKMESSAGE() with how=M_DONTWAIT(1) at line 913 in file /usr/src/sys/netgraph/ng_pppoe.c ... netgraph/pppoe is used by ppp to connect to my ISP . My last working kernel was built on May 31 . Thanks, if you know how to repair this. Uli.
