[Bug 29384] Slow switch between TTY1-TTY6 with /dev/fb0 or X11 involved

https://bugs.freedesktop.org/show_bug.cgi?id=29384

--- Comment #26 from peterle@hottemptation.org 2010-08-16 02:18:12 PDT --- In Comment 11 I describe a workaround, which seems to be based on Bug 27744. Boot up -> pm-suspend -> resuspend -> switching works fine

This requires a plug off power-cord, my laptop must run only on battery at the time! I think this is no wonder, because the bug was introduced with that commit: Date: Fri May 7 15:10:16 2010 -0400 drm/radeon/kms/pm: rework power management

Now it gets funny: If I replug the power-cord, the "slow-switching" appears again!
