Because, in this case, user space programs have no chance to run
correctly, only kernel space has chance to do something, for example,
calling machine_restart();

I suspect that some program is hogging the memory system, and system is
busy swapping to death, but I can't make sure that because the console
is locked in this situation. Before I find the culpit, I have to reboot
it when the system is stuck.
