OK :) I also use preempt + lock-break. Preempt patch alone is not good enough for our applications. >Anyway, with this combination you don't need the low-latency patches >anymore (according to www.tech9.net/rml/linux): <snip> He is probably right. Although lock-break patch wasn't updated for some time. Andrew Morton's low latency patch seems to be more up to date ... I'm thinking about trying it instead of lock-break or maybe just full patch set from (http://members.optusnet.com.au/ckolivas/kernel/). It probably will require some PPC mods though...
