That's weird. I'll try and find out what has changed and why.To my surprise, I find that it no longer emits that warning.
rpi_update install the latest versions of things like the kernel, firmware, and bootloader that are still undergoing testing. There used to be a big warning when you run it that it can break things.
In case it short-circuits your investigation...
I made a post in May2024 that had a copy'n'paste of the previous Warning - viewtopic.php?t=371573&hilit=rpi+update#p2225788
Referring to the source online at https://github.com/raspberrypi/rpi-update it looks as though there was a Commit in September 2024 for which this change might have been an indirect and unintended consequence? (But I'm not good at cherry-picking changes in Github repos, so I could be wrong...)
