I get this funny error message in both my laptops running Leap 15 some times after they wake up from hibernation:

I don't know what qualifies as strange power saving mode. I use hybrid suspend, when closing the lid, but this error also happens when I hibernate manually and it does not happen every time. The kernel behaves perfectly well otherwise, despite being dazed and confused.
Has anyone seen this and should I worry about it or report a bug?
Yes, I have seen it for years, on my two laptops.
