I will look at the problem but I think you should recompile your kernel
with in-kernel XICS or use the kernel shipped by the distro you use.

Also please try with a core supported by pseries :
/* 970 */
"970_v2.2",
/* 970MP variants */
"970MP_v1.0",
"970mp_v1.0",
"970MP_v1.1",
"970mp_v1.1",
you should be fine with these.
Thanks,
