[Xen-devel] Unable to bring up Mini-OS on x86_64

["Puthiyaparambil, Aravindh" <aravindh.puthiyaparambil@xxxxxxxxxx>]

I am getting the following error when I try to bring up Mini-OS on x86_64 Xen 
(unstable: 9994). It is dying in xc_linux_build() causing xend to fault and 
restart. Any clue why this happening? Has something changed in the builder that 
Mini-OS needs to be aware of?

PS: I tried reverting changeset 9993 (Allow linking of mini-os with 
application-specific object code), but still got the same error

Thanks,
