I am working on backports of all the O(1) scheduler changes in 2.5, the pending changes, and some other misc. bits. I also have versions of the migration_thread and affinity stuff for 2.4.
I will release a general O(1) patch and a patch for -ac soon - hopefully tomorrow or Monday. I have no idea if it fixes the problems you are seeing, because I have no idea what caused a regression in the O(1) code.

Good to hear ;)

That is the point of 2.5 :)
Development => !Stability and people need to start using 2.4 to get work done, not reap faster and faster benchmarks times. I seriously suspect 2.4 is performing fine right now for what you are doing, anyhow.
Also, a lot of VM work is happening in 2.4 (and not in 2.5 even, at the moment). 2.4.19-pre has seen a few of the -aa bits merged and should see most of the others in due time.
There is also Rik's -rmap for 2.4 ...
