Many piglit assertion failures in radeon_unmap_renderbuffer
Submitted by Ian Romanick

While doing other things, I noticed quite a few piglit tests crashing with
radeon_fbo.c:454: radeon_unmap_renderbuffer: Assertion `ok' failed.
This occurs when r100_blit fails. Just skimming the code, there are a LOT of reasons that r100_blit could return false, so it seems like there should be some fallback path. Some (perhaps all?) of the failures also log
WRITE DOMAIN RELOC FAILURE 0x1 6 4
Some tests that fail in this manner are:
bin/fbo-depthstencil copypixels default_fb -auto bin/stencil-drawpixels -auto bin/texsubimage -auto bin/tex3d-depth1 -auto -fbo
There are many others. On my last run there were 39 crashes (out of 1072 tests not skipped), and most of those seem to be this assertion.
If it matters, this was on:
