2.3.99pre8 + Oops

[sampsa@staff.netsonic.fi]

 Hi,

here is a dump for a crash on production 2.3.99pre8 non-SMP NAT server.
On boot, the ip_conntrack module says that it can handle max 2048
connections, it is possible that this was reached. A option to overwrite
the default memory usage would be nice, because this machine is dedicated
to run NAT & routing and has lot of memory wasted unless used for these
purposes.

Here is the dump, copied by hand, so you can expect minor errors, hope
there aren't any bad ones.

I dunno if this message falls under netfilter or linux-kernel list, I try
netfilter first due the nature of this Oops.

 Oops included:

ksymoops 0.7c on i586 2.3.99-pre8.  Options used
     -V (specified)
     -k /proc/ksyms (specified)
     -l /proc/modules (specified)
