-rc2-mm2 would be nice to test - there are a number of new interactivity fixes from Con being test-driven in -mm right now. In particular, these patches were added in -rc1-mm4. These are the patches in question:
sched-adjust_timeslice_granularity.patch requeue_granularity.patch sched-remove_interactive_credit.patch
you can download them individually from:
http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.10-rc2/2.6.10-rc2-mm2/broken-out/
so if these symptoms still occur with vanilla -rc2-mm2, could you try to unapply them, in reverse order? (there might be rejects when you try that, due to patch dependencies - let me know if it doesnt work out and i'll do an undo patch.)
