Pick 2.4.13. It should work fine on 2.6.18 kernels. Unless you need IKEv2 functionality (not likely) or hardware

2.4.13 is the last of the 2.4 series. 2.6.x still has a few small bugs. It might not hit you, but you
can avoid them for now by using 2.4.13.

3.x is currently a side branch. Ideally it will merged into the 2.6 tree. But it all depends a bit on where
crypto hardware acceleration in the Linux kernel is going to. (OCF vs acrypto)

That looks like a KLIPS bug.... You could try comparing some code, but it's probably not an easy
bug to find and fix.
