From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

It's probably best to try that with a live CD.

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

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