#51 ATI Radeon freaks out with 2.6.7+2.0.0.88

No

Screen is garbled on all consoles (though the
psychadelic patterns are different between text and X),
and eventually machine locks up -- Alt-SysRq doesn't work.

2.6.6+2.0.0.74 works flawlessly.

AGP reinit incompatibility?

    Additional (possibly helpful) information:

    * Same X software between 2.6.6 and 2.6.7 (I'm running
    kernels in parallel).

    * 2.6.7+2.0.93 has the same problem, but I can switch over
    to a text console, login and restart X _successfully_ while
    blind.

    If you edit kernel/power/suspend2.c and change calls to
    device_suspend(3) to device_suspend(4), does the issue go away?

    Regards,

    Thanks for getting back to me -- can't subscribe to
    swsusp-devel, for some reason.

    No, you're suggestion didn't work, and perhaps made the
    problem slightly worse -- couldn't restart X after resuming.

    Okay. That's good. The change from 4 to 3 is supposed to be the right
    thing :>. Are you able to apply 2.0.0.74 to 2.6.7? There'll be a few rejects,
    but I don't remember them being a great pain to fix. If you can't I can try to
    provide you with a patch, but it won't be immediate.

    I couldn't get your suggestion to work (OOPSes all over the
    place), but I forward ported the drm stuff from 2.6.6 to
    2.6.7, and now swsusp2 works great!

    FYI, I spotted a change about "ring buffers" or something
    like that concerning Radeon drm in the 2.6.7 ChangeLog.
    That might adversely affect swsusp2 ... *shrug*
