Prevents radeon_crtc_handle_flip() from running before
radeon_flip_work_func(), resulting in a kernel panic due to the
BUG_ON()
in drm_vblank_put().

Does patch #2 alone fixes the problem as well?
With #2 alone I get this during boot up (before plymouth):
[...]
[ 15.259867] [drm:radeon_crtc_handle_flip] *ERROR*
radeon_crtc->flip_status = 0 != RADEON_FLIP_SUBMITTED(2)
That's the original patch I sent to you along with two others for
testing. The patch I submitted in this series has these messages
downgraded to debugging messages, as they just show the patch
preventing
bad stuff from happening as designed.
The question is, can you reproduce the panic or the 'impossible msc'
lines in the Xorg log with only patch #2?
Oh, shit sorry.
I'll redo in a minute before I went to bed!

But with Michel's #1+2 and 3 I got this in Xorg.0.log:
(See Xorg.0.log.old.xz)
(EE) [mi] EQ overflowing. Additional events will be discarded until
existing events are processed.
That may not be directly related to the page flipping issues.
