Then might I recommend an Occam's Roazor approach to this? Compile a
number of kernels from the one which worked up to the one which doesn't.
Reboot the backup; test; if it doesn't happen then you know the change
cam later than the kernel you're running.

Not the fwmarks! For completeness I meant "clear out the IPVS rules on
the backup but leave the modules loaded".
