I think it will change because: I'm not going to use the same distro, but change from Fedora to Suse.
What's more, I've managed to compile this same kernel source time ago, so something wrong must be happening :-).



One workaround is to look at which module is erroring (in your case an IDE bit of code). And then see if you live without that code (disable it).


Also if you are using a redhat .config preprovided file then it tends to build everything as a module - in my experience this becomes very fragile. I prefer to have few or no modules (and this tends to fix a lot of compile probs as well)

As I said, I'll get Suse 9.1 Prof soon (the 10th most probably). I'm curious about the PSCHED_CLOCK_SOURCE value. Is it wrong or deprecated the default Fedora's value (PSCHED_JIFFIES instead of PSCHED_CPU)? Or is it just that you have to compile your own kernel in order to get ingress rate policies working fine ?



I'm a BIG fan of gentoo. You never need to upgrade again...! (Debian sounds nice as well)


I think the psched_clock_source code just changes how the scheduler works out how often to fire. Basically its hard to get accurate high resolution timers on most operating systems. I haven't studied the details, but assume the CPU method gives more accurate results, perhaps at the expense of more CPU required..?
