I certainly agree with you it is hard labour, and YMMV for the actual time needed. Initially I tried to work around with small patches before and after the ones from developerworks to make it work on top of the SuSE specific patches, but ended up doing a lot of hacking in the IBM ones too. But I don't agree on your statement about SMP - on the contrary, the OCO modules only work for SMP kernels. The thing that may have confused you is that the OCO modules for the timer patch have been build for a kernel with a different version name. If you build the kernel (like SuSE do) through the rpm package you get a 2.4.7-SuSE-SMP kernel, where going throug a 'make' in /usr/src/linux will get you a 2.4.7-SMP version. A '-f' on the insmod will do the magic for you, but prevents the automatic loading of the modules (so you have to get into some of the /etc/init.d/ scripts for that. Rob
