    Default 2.6.34 and power management

    Wich kernel I need to apply this patchset (http://people.freedesktop.org/~agd5f/pm2/)

    With linus-2.6.34_rc4 there are many rejects
    With drm-radeon-experemntal there are rejects too

    Does any body can make this patchset usefull for linus-2.6.34_rc4?

    Merge drm-radeon-testing-pm2 from this repo into your git tree:
    http://git.kernel.org/?p=linux/kerne....git;a=summary

    So the command should be:
    Code:
    git pull git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-radeon-testing-pm2

    I got d-r-t + d-r-t-pm2 branch pulled, and I got hardlock imidietaly after starting Xorg when dynpm or dynclks and modeset, and even it hardlocks after writing a few commands under KMS console.

    I got T60p with r500 (FireGL V5200), and 64bit kernel.

    That's because pm2 enables memory reclocking, which we are not ready for. We have to block access to memory before reclocking it. If not, we will get lock-up (as we do).

    I were reclocking memory even to very low values before, and only problems I got were fuzzy screen on low clock and it never hanged up.
    And I believe only one of dynpm/dynclks reclocks, but both causes hang! (but didnt looked at code)
