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-ke45wuyidarlnthfbtcg/D1449.diff

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.
