--- Comment #40 from Aaron Watry <awatry at gmail.com> ---
Can you apply the following LLVM 2 code series, build the latest upstream
libclc version, and try again?

LLVM Patch series:

Libclc:
git clone http://llvm.org/git/libclc.git

With that, and the latest mesa git code, I've managed to run bfgminer for ~5
minutes on a Radeon 5400 without a single lockup.  This same GPU used to lock
up within 5 seconds of starting: bfgminer -v1 --benchmark
