NEW_TIME_C is set. URL to the patch is: http://www.kernel.org/pub/linux/kernel/people/rml/preempt-kernel/v2.4/preempt-kernel-rml-2.4.19-2.patch We ultimately want to add in real-time support, such as Ingo's O(1) scheduler - if this is 'complete' for MIPS. I don't know if it would be better just to go for this in one hit, or if we'd need the preemption sorted out anyway first. Or should we just go to a 2.5.x kernel instead?

At minimum, you need to use NEW_TIME_C, Or else you have to take a lot of stuff youself. 2) Not sure if all MIPS patches are in RML's patch. If you pass the URL pointer, I can take a look. 3) Even with all above taken care of, there are still unsolved issues (such as math emul not pre-k safe, some cache operations, etc). However, these problems usually are much harder to show up. You won't see them unless you delibrately want to. :-) Jun
