Just did a poweroff on the pcDuino3 Nano. Did nothing after logging in. No upgrades nothing. Got the following messages on the TTY console after lots of shutdown messages: [ 7544.587424] reboot: Power down [ 7546.646239] i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0 [ 7547.177766] systemd-shutdow: 4 output lines suppressed due to ratelimiting [ 7547.191003] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000000 [ 7547.191003] [ 7547.200158] CPU: 0 PID: 1 Comm: systemd-shutdow Tainted: G W 4.10.0-0.rc4.git1.1.fc26.armv7hl #1 [ 7547.210060] Hardware name: Allwinner sun7i (A20) Family [ 7547.215310] [<c021a378>] (unwind_backtrace) from [<c0214c9c>] (show_stack+0x18/0x1c) [ 7547.223058] [<c0214c9c>] (show_stack) from [<c05bdfc4>] (dump_stack+0x9c/0xd0) [ 7547.230287] [<c05bdfc4>] (dump_stack) from [<c0397230>] (panic+0xd0/0x26c) [ 7547.237167] [<c0397230>] (panic) from [<c025fa60>] (do_exit+0x678/0xce4) [ 7547.243870] [<c025fa60>] (do_exit) from [<c0283bc4>] (SyS_reboot+0x184/0x208) [ 7547.251007] [<c0283bc4>] (SyS_reboot) from [<c020fe20>] (ret_fast_syscall+0x0/0x1c) [ 7547.259354] ---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000000 [ 7547.259354]
