The issue you are seeing now seems different, though afaics. The fixing commit from the above reference, 8be8f932e3db ("kvm: ioapic: Restrict lazy EOI update to edge-triggered interrupts") was applied in v5.7-rc3, which was as well backported to v5.6.13. Now you kernel is tained, can you check if you see the issue as well when not loading the modules which taint the kernel? Next, if it still does show up, does it show up as well in current mainline?
