Hi all,

I recently get oopses with a custom 2.4.26 kernel (freeswan patches and most of the "safe" netfilter POM stuff), but only on one machine and never on any other machine.

Tainting is because of the ppp_mppe module, which has a BSD license, but is not used in this case.

The syslog reads:

So it seems to be somehow related to inet_setsockopt. Since this is a fiewall, I have limited debugging capabilities on the machine. If necessary, I might be able to get the ksymoops.
