[arch-general] kernel: do_IRQ: 7.34 No irq handler for vector - once a minute beginning ~ 4/27?

All, I have a new kernel message showing up in the logs once a minute that seems to have began about April 27, the message is: kernel: do_IRQ: 7.34 No irq handler for vector From a bit of research, there are suggestions about adding "pci=nomsi,noaer" to the kernel command line, which I'll try, but my question is -- any idea why that should suddenly start and is the "pci=nomsi,noaer" the proper fix? -- David C.
