Do you get any  error or output or does it just fail silently?

I have never seen this unless the grub configuration was 
wrong/incomplete. I can't think of a reason why you shouldn't at least 
see the first couple lines of Barrelfish output even if the platform 
isn't supported.

As for known-to-work hardware: we regularly run Barrelfish on Intel Xeon 
e5-2670 v2 and Intel Xeon E3-1245 v3 CPUs installed on Intel S2600GZ and 
S1200RP mainboards. There are a few known issues with systems that have 
large amounts of physical memory installed (you can try the attached 
patch as a band-aid for that issue for now).

Best,
