I don't know about XFS-on-Linux, but I've used XFS on IRIX for ten years now and I've probably had a hundred unclean shutdowns. I've only once had data corruption, and that was recently when there was some kind of dirty power event that threw five disks and two controllers in my array.
Similarly anecdotal, a dormmate of mine ran XFS for a while. Then one day he spilled some water near the extension cord and guitar amp he'd plugged into his UPS. In a frantic move he unplugged the wrong cable during an emerge and discovered a number of binaries full of ^@ (null).
When I asked friends about it, a veteran UNIX admin mentioned that IRIX was designed for SGI machines, high end all of them. Among their notable features is a power failure notification system capable of taking corrective action, because the power supply was designed to their specifications, rather than the PC market's. The same guy pointed me to SGI's own statement on the subject, archived by our good friends at archive.org:

You'll note the question has been updated, but doesn't detail how it was fixed:
