I haven't heard of anyone taking upstream kernels and actually using them
for production work in a long time. It's mostly just a few folks keeping ia64
alive "just because" these days. I doubt any of them have an SGI Altix
to test on (so realistically Altix was probably broken upstream many releases
ago).
