maybe the 2.4 series is somewhat outdatet, but nevertheless used in several embedded systems and also with your preemption patches. During some investigations, we found out that the patches found on http://www.kernel.org/pub/linux/kernel/people/rml/preempt-kernel/ contain a severe bug, when using the patches on PPC systems.Yes, it's a known problem with rml preempt patches - DON'T USE THEM on PPC. I sent him similar patch _two_ years ago - nothing happened. MVL tree is IMHO better place to get preempt stuff for 2.4 - it's actually tested and works.yes, because there are more changes then only the forgotten '{'
You're right, there were other (not so obvious) problems which rml patch (like preempt_enable_no_resched() in irq.c::preempt_intercept()), maybe others I don't remember now)... -- Eugene
