We do not have any 2.4 version but the backport shouldn't be hard. When Joel did this patch it was also in order to get realfeel working. The point is that it seems on ia64 measuring latencies using the perfmon capabilities of the processor is a much better idea. Peter Chubb even developed a small realfeel equivalent that does exactly that! It should work both on 2.4 and 2.5 kernels. You can find it on the perfmon homepage and at this address: http://www.gelato.unsw.edu.au/patches/realfeel4.c Cheers Eric
