I also just installed 4.4.0-131.157 over 4.4.0-128 (that I reinstalled that and booted on it to avoid the 4.4.0-130 bug) and it seems like it is working again in a Xen VM with PVGrub. My issue was identical, but with a different error message (bad memory access error in the very first initrd boot phase also pointing to a badly built initrd.img).
