Why is there no side effect? AFAIK, kexec goes through the shutdown path and you are leaving a PCI device enabled during kexec boot which can corrupt the booting OS memory. I don't think you can generalize a behavior based on a few quirky devices. You should be quirking only the device that has a problem rather than changing the behavior of all other platforms.
