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

FeFiFoFum · December 24, 2020 at 5:23 AM

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:>

[53266.365393] systemd: 37 output lines suppressed due to ratelimiting

"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

ghtester · December 24, 2020 at 3:17 PM

I am usually using just:

reboot

or (if Kodi is running)

kodi-send --action="restart"

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.
