OOPS on bringing down ppp

[Mark Ellis <mark.uzumati@virgin.net>]

Hi all, consistently getting the following when pppd is terminated. Happens
in 2.4.0-test11, fine in 2.4.0-test9, don't know about test10. Same happens
for pppd 2.4.0b4 and 2.4.0, both recompiled for test11. Is this related to
the modutils incompatability (modutils 2.3.19) ? 

CONFIG_PPP and CONFIG_PPP_ASYNC are built in, CONFIG_PPP_DEFLATE and
CONFIG_PPP_BSDCOMP as modules, but oopses whether they are loaded or not.

ksymoops 2.3.4 on i686 2.4.0-test11.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test11/ (default)
     -m /usr/src/linux/System.map (specified)

Any ideas ?
