As noted in #7603, the issues are most probably due to a major scheduler rewrite from 2.6.22 -> 2.6.25.

I'm very open to including Ingo's -rt patches in our kernel for a future release if we see that it improves overall responsiveness of the system. ~Deepak -- Deepak Saxena - Kernel Developer - [EMAIL PROTECTED] _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
