I upgraded from 6.2.2 to 6.2.4 two-three days ago and I haven't really been watching the logs much. Since the upgrade to 6.2.4 I have noticed the following in my system log twice now, once this morning and once this afternoon (even after rebooting in between):   Nov 11 17:12:08 Node kernel: irq 16: nobody cared (try booting with the "irqpoll" option) Nov 11 17:12:08 Node kernel: CPU: 0 PID: 11501 Comm: emhttp Not tainted 4.4.30-unRAID #2 Nov 11 17:12:08 Node kernel: Hardware name: Gigabyte
