Really broke something "Illegal Instruction" for shutdown -r now

  • Has anyone ever seen this before?

    I had to use some very obscure commands, to reboot my Pi from SSH. Something went pretty critically wrong with my system and I'd love to identify the cause.


    This isn't a critical problem as I have now rebooted it, but I'm very curious what could cause this?


    "systemctl start reboot.target"

    Same error.


    Dmesg:>

    "reboot" same error.


    "telinit 6"

    Same error :(


    Ok the ONLY way I could remotely reboot was this.



    Code
    $ sudo echo 1 > /proc/sys/kernel/sysrq


    Code
    $ sudo echo b > /proc/sysrq-trigger


    The last thing in Kodi.Log was over 24 hours ago.

  • Have you tried?:


    Code
    shutdown -r now

    Yes, that's the first thing I tried. All that same error.


    I'm more curious why it occurred and now how to reboot it. I've managed to reboot it with 2 obscure commands that google tells me, I shouldn't get in the habit of using.

    (see my full post - end)

  • So if the issue is still the same after reboot, it looks your LE installation is somehow broken (maybe the SD card issue) because this problem does not happen on a clean LE. Check the dmesg output if there're some errors, the few published lines from kodi.log does say nothing.
