I patched llvm with
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20130812/184089. html
using
patch -N -p1 -i p2.patch
But still got lock-ups. Any hints? :/
I just did a fresh install of Ubuntu 3.04 64bit on an Athlon 64 with a radeonsi 6850.
I did a checkout of LLVM/clang master and applied only the following patch: http://llvm-reviews.chandlerc.com/file/data/lzktdebskepaizauyiqg/PHID-FILE-k...
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.
