>From your 4.14 log: Feb 19 09:48:06.843173 kodi kernel: CPU 0 irqstacks, hard=e9b0a000 soft=e9b0c000 Feb 19 09:48:06.843216 kodi kernel: spurious 8259A interrupt: IRQ7. Feb 19 09:48:06.843258 kodi kernel: Console: colour VGA+ 80x25 So this has been there in 4.14 already just the detection mechanism has changed due to the modifications of the interrupt vector management code.
