In PFIFO dump it appears that game channel was already killed, and it tried
switching to DDX channel.
I have another older dump of PFIFO that, where its not killed, and once again
there is attempt to switch to channel #2 which is for DDX.

In fact channel mapping (which just happens to be this way):

Without compiz:

1 - framebuffer - idle (while in X of course)

2 - xserver EXA - occasional bursts while game runs. on screen panel updates
(clock,etc..) mostly I think

3 - xserver AIGLX - not used at all, as I don't launch such clients
4 - game


With compiz:


1 - framebuffer
2 - xserver EXA
3 - xserver AIGLX

4 - compiz - again, short bursts of activity time after time while game runs,
probably to redraw windows that X clients (the same panel for example) writes
to.

5 - game


Also channel 0 seems not to be used at all, it with channel 127 are sort of
special.
