Which board did you try? I just run it on i.MX8MN-EVK board, no such failure: root@imx8mnevk:~# uname -a Linux imx8mnevk 5.6.0-rc7 #621 SMP PREEMPT Sat Mar 28 19:56:30 CST 2020 aarch64 aarch64 aarch64 GNU/Linux root@imx8mnevk:~# dmesg | grep fail [ 0.719353] imx-sdma 302b0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2 [ 0.941304] calling net_failover_init+0x0/0x8 @ 1 [ 0.941310] initcall net_failover_init+0x0/0x8 returned 0 after 0 usecs [ 1.135885] calling failover_init+0x0/0x24 @ 1 [ 1.135897] initcall failover_init+0x0/0x24 returned 0 after 6 usecs root@imx8mnevk:~# Thanks, Anson
