TODO: Nuke *all* distro-specific guides on libreboot.org. Instead, move these
instructions to the wiki pages of these projects, on their websites. The reasons
are explained in the above issue page.
Rebooting system in case of freeze
===================================
Linux kernel has a feature to do actions to the system any time, even
with it freezes, this is called a
[Magic SysRq keys](https://en.wikipedia.org/wiki/Reisub). You can do these
actions with Alt + Sysrq + Command. These are the actions:
* Alt + SysRq + B: Reboot the system
* Alt + SysRq + I: Send SIGKILL to every process except PID 1
* Alt + SysRq + O: Shut off the system
If some of them don't work, you have to enable it in the kernel
command line paramter. So append `sysrq_always_enabled=1` to your
`GRUB_CMDLINE_LINUX_DEFAULT` in `/etc/default/grub`
You can also run `# sysctl kernel.sysrq=1` to enable them.
