Hi,
well, as far as I am aware, no one had encountered a CPU lockup on the shipped out prototypes so far, and we're all using TILER with the zmatt patch for transparent rotaton.
I've got no idea why - but it seems to work fine here :)

Do you think you can find time to take a look at Matthijs implementation and what he really is doing to get our demos working flawless (despite errata)?
Well, you can't avoid the errata. The errata says that if you access TILER mapped memory with CPU, the device may lock up.
I will review mainline patches sent to dri-devel, but otherwise I'm not planning to work on TILER any time soon, unless we figure out a way to deal with the dmabuf problem.
