Re: [Xen-users] xen 2.0.7 on VIA C3 (EPIA)

[Rafael Ferreira <lists@xxxxxxxxxx>]

I'm on the same boat with a VIA Samuel C3. I can't get 2x  patched and
the 3.0 series won't boot. 

I don't think the C3's are high in the priority list but It would be
awesome if one of the developers gave them some love one of these days.
