Dmesg: "can't derive routing for PCI" error


Above error found after crash of system (crash as in i3 desktop environment locked up; moving mouse → smearing of screen and couldn’t even launch a functioning terminal window). Already searched f36 and kernel tags. Similar messages noted in google with AMD CPUs but none that I found with old mac (2009 Mac Pro, Nehalem processor). Current kernel is 6.1.15-100.fc36.x86_64. Not sure of course if the above symptoms and the error report are related, but thought I’d ask anyway about the error. My thanks,
