--- Comment #7 from Bruce Cherniak <bruce.cherniak at intel.com> ---
I'll take a look into this.  The first thing I notice, is that you are running
with the DRI drivers.  Most of our customers use only the standalone GLX
drivers.  We do not test DRI heavily.

You appear to be running a debug build (from the stderr output) of either mesa
or llvm.  Does this occur with release build as well?  And, is there a reason
you are running with a debug build?

>From the very complete BT (thank you!), it appears that the api thread is
waiting for a fence to complete, but all of the worker threads are sitting in
idle -- suggesting that the fence should be complete.  Once you hit this stuck
loop, can you step into swr_is_fence_done and "print *fence".

Thanks.  I'll report back as soon as I find anything.

(assigning back to Gallium/swr until something suggests otherwise)
