reboot: Segmentation Fault

I have no idea how I ended up in that situation, but the entire system of my odroid locked up earlier this week. Not even rebooting was working. Most of the commands failed with a segfault or bus errors.

root@odroid:~# reboot -f -r now
Segmentation fault

After a quick search, I stumbled over the Unix&Linux Stackexchange where someone says – Try to reboot with the magic SysRq key. Wait what?

echo b > /proc/sysrq-trigger

The SysRq-trigger has a ton of use cases that are documented in the kernel documentation

the b flag triggers an immediate reboot of the system without syncing or unmounting your disks. And it worked like a charm. 🎉
