Thanks for pointing this out. Just a question: In this case (bug on application on mapping BOs/VAs) shouldn't we have a crash using other drivers? With r600g we don't have this problem (tested with an ARUBA A10 5800K), just on radeonsi (at least on the tests I performed, which are basically running "Antutu Benchmark" and some other apps). However r600g/other drivers/hardwares can handle this in a different manner of course, which could explain why we don't experience this on other hardwares. > > Anyway Michels patch is clearly a good idea. I've uploaded an testing Android-x86 ISO with Michel patch applied. It's using Lollipop (5.1), Mesa 10.5.4, Kernel 4.0.3 and LLVM 3.5svn (AOSP). It's also enabled for radeonsi (this is the main purpose). In case anyone wants to test it on a radeonsi hardware, here's the link: https://drive.google.com/file/d/0Bx12U5yGNcQCRWdoWWtNdC0weW8/view?usp=sharing Thank you all! pstglia
