Searching the web, I see that this is possibly related to some sort of power management issue, and a possible solution might be to add pcie_aspm=off to my boot options; but I found no OpenSuSE-related hits, so I thought I’d check before doing this.
This suggests to me that your problem is not distro-specific, and is more likely related to settings or drivers provided by the mainline kernel. There is a chance the problem might be Desktop related(a medium possibility) or the base openSUSE distro(IMO very unlikely), depending on how your consoles are invoked.
I’m curious by your statement “all text consoles are continually flooded”
I might understand how this error might display in your system log, but not in “all text consoles”
Are these real tty consoles or windowed consoles or both?
Are you saying that just invoking a console, you see the error message multiple times or are you opening a log file or system log?
Regardless whether your fix works or not, it might be worthwhile to add your result to an existing bugzilla you’ve found or create a new bug in the opensuse bugzilla, https://bugzilla.opensuse.org
I found this very strange, because I have been running OpenSuSE on this laptop since V11 with no problems. But after booting a few times the problem went away by itself. (I hate when that sort of thing happens.)

Yes, the messages were scrolling at high speed on all of the consoles tty1–tty6 that are available using CTL-ALT-F1–F6, without even logging into them, let alone examining the logs.
