From Jaco Kroon:
I've got a piece of code that seems to reliably cause the kernel to panic, looks
like a problem somewhere down the netlink core. I've been trying to use
NETLINK_FIB_LOOKUP but so far the closest I've come to success was a kernel crash.
A patch for this issue has been included in build 2.6.18-8.1.4.el5.
