Subject: drm/radeon/kms regression: 2.6.33-rc2 does not boot

Hello,

One of my systems works fine with 2.6.32, but hangs when trying to
boot 2.6.33-rc2.  Git bisect says
7923c615b811945a9d9f456c92a7a32c34167458 is the first bad commit:

    drm/radeon/kms: make sure mc is initialized before mapping blit bo

    We need to make sure the the MC is intialized before we map the
    blit shader object on r6xx+.

(So the problem was already present in -rc1.)

The last message I see during a 2.6.33-rc2 boot is about attaching a
disk.  Then everything stops until I press Ctrl-Alt-Del.  With a
working kernel, the next thing would be switching the console to a
higher resolution mode.  The graphics card is 

01:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4350]

Please Cc me directly on replies.

Andrei
