--- Comment #3 from Jesse Barnes <jbarnes at virtuousgeek.org> ---
Can you attach to the hanging processes with gdb -p and check the backtraces? 
If we're not seeing a GPU hang, the process must be hanging on something else,
maybe waiting for an event or potentially a locking problem in the kernel
(sysrq-t would help track that down; depending on your kernel config that's
easy or hard to do; best google around for your specific distro instructions).
