Hi Daniel!

It sounds like you have problems with your kernel-logs... do you receive
any kernel messages at all? i dumped klogd at all and using the following
syslog-ng-directive as source for my kernel messages:

---

source srck { pipe("/proc/kmsg"); };

---

It works w/o a flaw for me and makes the klogd obsolete, another
application which can't break  :)
