Any luck with Redhat Enterprise kernel?

I'm getting panics in ip_refrag with it now.     It's stock RHEL 
2.4.21-09 with ebtables-5 from 2.4.24 on it.     

I had to fix a couple parts of the patch to make it compile.   The 
rtable changed and instead of having a pmtu variable in the structure 
it's now referenced by:

__fake_rtable.u.dst.metrics[ RTAX_MTU ] = 1500;


I can start up a bridge and get everything flowing nicely,  it's only 
when I do anything with the conntrack  module.  iptables -L -n -t nat 
will panic in this same spot every time if the bridge is up.

Any ideas?

thanks,
Ian
