Problems with pppd

[Eric J. Christeson]

I spent this past week updating my Dragonfly 1.2 box to 1.4 source
downloaded on Jan. 20, 2006.  I am using dialup with pppd.  The
upgrade went w/out problem except that I can't access the Internet.
The ppp chat script seems to connect fine, but trying a ping causes
ping to hang.  It is only the ping process, the rest of the box is
quite usable.  The ping process will not respond to ^C or kill -9.  If
I attach gdb, gdb hangs also, but is killable.  I have the kernel
compiled with DDB, but I haven't figured out how to get anything
interesting out of it yet.
Attached are the boot dmesg and kernel config.

Thanks,
Eric
