    SubjectRe: 2.6.25-rc7-git2: Reported regressions from 2.6.24

    > Subject : 2.6.24-git15 Keyboard Issue?

    Rafael, we can close this bug i think. The group scheduler related
    interactivity problems in early .25-rc were resolved via:

    | commit 62fb185130e4d420f71a30ff59d8b16b74ef5d2b
    | Author: Peter Zijlstra <>
    | Date: Mon Feb 25 17:34:02 2008 +0100
    | sched: revert load_balance_monitor() changes
    | Namely:
    | - very frequent wakeups on SMP, reported by PowerTop users.
    | - cacheline trashing on (large) SMP
    | - some latencies larger than 500ms

    that includes Xorg's fragility to certain types of delays. It should be
    resolved by now and i havent seen it resurface.

    we are now back to the 2.6.24 state of things. Which isnt as perfectly
    interactive as the non-group-scheduler 2.6.24, but which is still more
    interactive than say 2.6.22.

    Peter is working on improving it even more, but that's 2.6.26 material.
