Cubieboard2: I got a flood of these messages. The full message is: rc rc0: IR event FIFO is full! I googled it and this seems to be related to the A20 chip. My boot starts with: U-Boot SPL 2016.09.01 (Oct 19 2016 - 13:46:44) DRAM: 1024 MiB CPU: 912000000Hz, AXI/AHB/APB: 3/2/2 Trying to boot from MMC1 U-Boot 2016.09.01 (Oct 19 2016 - 13:46:44 +0000) Allwinner Technology CPU: Allwinner A20 (SUN7I) Model: Cubietech Cubieboard2 Also I am on the IETF network so I am quite public and am getting hit with interesting traffic. Like: conntrack: generic helper won't handle protocol 47. Please consider loading the specific helper module. And I really don't want to handle protocol 47, it is a attack vector. thanks
