dmesg with nodma + notiling

Oops sorry I forgot about the tiling patch. Unfortunatly it doesn't help,
with it I can see egltri_screen triangle but the monitor reset, and
eglgears_screen still display garbage.
Attached is the dmesg with the 2 apps tested.

By the way does clover use dma ? Clover runs fine, at least in simple case, but
with inputs and output verification, and back to the commit that introduced
hawaii support.
