How does Linux move from an awake machine to a hibernating one? How does it then manage to restore all state? These questions led me to read way too much C in trying to figure out how this particular hardware/software boundary is navigated.

This is certainly an interesting feature, though my one use case has become much less relevant now that systems boot so quickly.

Perhaps if you have long running jobs and no implementation of state saving it could find applications.

Boot times on AM5 are soooo slow due to some memory training feature of DDR-5, even after following many suggestions for settings. It appears to be a general issue with the platform, ~~so hibernation is very much back on the menu for me.~~

Duh, it won't matter since the delay is before POST.

On Asus motherboards you can enable 'Memory Context Restore', and it'll remember the training. Unfortunately it seems rapid changes in the weather make my system unstable with it on.

I have an MSI motherboard. Memory Context Restore shaves significant time off of boots, but it is still extremely slow. Just a hang before I see POST complete.

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.
