SubjectOOPS on bringing down ppp
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)
