I did a checkout of LLVM/clang master and applied only the following patch: <a href="http://llvm-reviews.chandlerc.com/file/data/lzktdebskepaizauyiqg/PHID-FILE-ke45wuyidarlnthfbtcg/D1449.diff">http://llvm-reviews.chandlerc.com/file/data/lzktdebskepaizauyiqg/PHID-FILE-ke45wuyidarlnthfbtcg/D1449.diff</a> Without that patch, libclc won't currently build for the radeonsi target. Along with that I checked out git copies of Mesa, drm, and libclc. I upgraded the kernel to 3.11 from the Ubuntu mainline ppa, but I didn't enable dpm (machine wouldn't boot with it enabled, and I was too busy to debug that). With this done and all of the aforementioned packages compiled and installed to /usr/local, I have been running 'bfgminer -v1 --benchmark' without a single lockup for 20 minutes now on a radeonsi 6850 that used to exhibit the same lock ups that we have been discussing, and which also seem to have been cured on the 5400 card I was esting on before.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
