The only issues I can think of are no huge page support and the igb_uio or kernel components may not build. Having no huge page support can be a performance hit, but you should use ?no-huge option. I know some people have it building on older kernels, but it has been many revs back. > > Thanks a lot! > > > James Regards, Keith
