It is possible that this is a problem with our mesa package, which does
not use LLVM for the Gallium drivers.  It might be worth changing this.

Unfortunately, this will result in quite a few rebuilds, so this change
would only be available in a few weeks.

Could you please send an email to address@hidden requesting that mesa
be built with LLVM for better performance of the Gallium drivers?
