I found a demo that has the issue, in the demos repository for mesa within the
src/demo folder the program 'reflect'.  After I start it up and press 's' to
see the stencil buffer the white plan blinks continuously.  Applying the patch
'fixes to wait on the bo and to free the va after the kernel' removes the
blinking, as does disabling va through the variable
ws->info.r600_virtual_address.

The other issue with the kernel reporting a va conflict is going to be a little
harder to reproduce because it appears to be caused by a race condition.

I'll still look for other demos that have the issue.
