Actually, the question is how to drop Linux in a kernel panic without breaking the system (so that it would work fine after a reboot)? Tested distro Ubuntu server 12.04, kernel 3.5.0. Of the methods found, only write to all /proc 1 variables.

Answer 1

echo c > /proc/sysrq-trigger

or a site with a description of vulnerabilities.
at noon, most often there is a code next to it, which drops the kernel in the demo

Answer 3

rm -rf /proc/*
