Fed-up Torvalds suggests disabling AMD’s 'stupid' performance-killing fTPM RNG

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 can't speak for other distributions, but Pop!_OS has had a "Refresh Install" option for a while now that does exactly this. This hasn't happened often, but there have been a couple of times when something borked my system to the point of making it no longer boot, and re-running the installer in "Refresh Install" mode got everything back and running within 30 minutes while preserving all of my non-system files; in particular this meant that I didn't have to re-download my Steam and other locally installed games, which is significant because they are the largest apps on my system.
