How to safely manually trigger a kernel panic?


I've been using Linux for 1.5 year now one of the reason is the number tux represented how many CPU core I have on boot, but I'm disappointed because they don't do that anymore, another reason is to experience kernel panic and I never got one how can I manually and safety trigger it?

Alt+SysRq+C, although your distro may have it disabled by default.

A fair warning though, safety is relative and crashing the kernel can be destructive. Make sure you have backups when breaking things.

You could write a small kernel module that just triggers one as soon as it's loaded

Linux reshared this.

The tux logo at boot is due to a kernel option. You can enable this if you like.
