For me it was that the PXE-ROM images f= or=20 the network cards were updated as well. Their size changed over the next=20 power-of-two size, so kvm needed to allocate less/more memory and changed=20 some PCI configuration registers, where the size of the ROM region is store= d. On loading the saved state those sizes were compared and failed to validate= =2E=20 KVM then aborts loading the saved state with that little helpful message. So you might want to check, if your case is similar to mine. I diagnosed that using gdb to single step kvm until I found=20 hw/pci.c#get_pci_config_device() returning -EINVAL. Hope that helps.
