Can anyone please help me understand what this tainted message might be from?

It lists so many things that I can not tell the source. I see iee80211 so I thought it might be a network packet, but than I see IRQ and also modules being listed so it is really convulated.

Ubuntu xenial with 4.15.0-43-generic kernel.

Note: I ran mem test for like 24 hours and had no memory errors
