Hi, now i understand . xics have to be build in kernel and is needed by qemu 2.9 with kvm. if is not present in the kernel have the issue that i been reported about xics. I make a test on ubuntu 16.10 and on 17.04. the two distro are ppc 32 and generic. i had build the stable kernel 4.10.5 two times with the same config the only parameter that i had change was the xics one was yes and the other was no.
On the two ubuntu version when i run kernel without xics i had the issue reported. if i run the kernel with xics enabled qemu 2.9 is working and was gave no issue. but ... on Fedora server 25 ppc64 if xics is present in the kernel the system (fedora) not run and freeze after the kernel bootstrap.
