Are there? I would easily accept that it might struggle with drivers, but what architectural reasons would stop XP working on brand new x86 hardware? The CPU should be backwards compatible, boot will be a little funky if you're on a pure UEFI system but some web searching seems to show people booting XP on UEFI with only a bit of awful hacks, ... and I'm blanking on what else would be a problem, honestly. Edit: Oh, just now noticing your comment about P/E cores being a problem. Maybe? I'm surprised that that would break it, but maybe if it's explicitly checking that the CPU cores all match or something? Still seems like a minor, self-inflicted, and easily-patchable problem? Not that it would handle P/E cores well, just that I'd expect it to run on them.
