Top Forums UNIX for Advanced & Expert Users what does the kernel panic mean? Post 302572591 by Corona688 on Thursday 10th of November 2011 10:36:52 AM

A crashed kernel writes no files... This is a safety feature preventing it from corrupting the disk.

Meaning, kernel panics don't get saved to disk, which is often unfortunate.

They usually get dumped to the raw VGA console. If you don't let your system start X11, you'll probably see them. You may need a digital camera or somesuch to capture the message since, as before, a crashed kernel writes no files.

You can also configure them to get sent to a serial port instead, I think, if your system has one, so a different machine or a serial printer can capture them.

SYSTEMD-GETTY-GENERATOR(8)				      systemd-getty-generator					SYSTEMD-GETTY-GENERATOR(8)

NAME
systemd-getty-generator - Generator for enabling getty instances on the console SYNOPSIS
/lib/systemd/system-generators/systemd-getty-generator DESCRIPTION
systemd-getty-generator is a generator that automatically instantiates serial-getty@.service on the kernel console(s), if they can function as ttys and are not provided by the virtual console subsystem. It will also instantiate serial-getty@.service instances for virtualizer consoles, if execution in a virtualized environment is detected. If execution in a container environment is detected, it will instead enable console-getty.service for /dev/console, and container-getty@.service instances for additional container pseudo TTYs as requested by the container manager (see Container Interface[1]). This should ensure that the user is shown a login prompt at the right place, regardless of which environment the system is started in. For example, it is sufficient to redirect the kernel console with a kernel command line argument such as console= to get both kernel messages and a getty prompt on a serial TTY. See kernel-parameters.txt[2] for more information on the console= kernel parameter. systemd-getty-generator implements systemd.generator(7). Further information about configuration of gettys can be found in systemd for Administrators, Part XVI: Gettys on Serial Consoles (and Elsewhere)[3]. SEE ALSO
