<pre>What a pity, my hope was that DRI3 will work more reliable than DRI2 on PPC
hardware.
I am using MATE 1.18.0. Freezes with DRI2+exa happen almost instantly when
reaching the desktop:
[ 1275.313543] radeon 0000:f0:10.0: ring 0 stalled for more than 10133msec

0x0000000000000432 last fence id 0x0000000000000433 on ring 0)
[ 1275.463941] Failed to wait GUI idle while programming pipes. Bad things
might happen.

DRI3+glamor either did not work out:
[ 143.438] (**) RADEON(0): DRI3 enabled
[ 143.438] (==) RADEON(0): Backing store enabled
[ 143.438] (II) RADEON(0): Direct rendering enabled
[ 143.439] (WW) glamor requires at least 128 instructions (64 reported)
[ 143.439] (EE) RADEON(0): Failed to initialize glamor.
