The great upgrade from Linux Mint v 21.2 to v 21.3 occurred early this morning while I was fixing breakfast. I get up early to open the house, and check on the creatures as well as my machines. I found the notice to upgrade on the Linux Mint Upgrade Manager, so I just kicked it off while I finished my morning chores. So far nothing is amiss, and if you sat me in front of two systems, one running 21.2 and one running 21.3, I wouldn’t be able to tell the two apart unless I cheated (cat /etc/os-release). And that, for me, is a wonderful thing. I’ve grown rather conservative about allowing change in my primary computer platforms. It would appear I’m in good company (in a way);

Just a note that I’m currently bisecting into this merge for a horrendous performance regression.

It makes my empty kernel build go from 22 seconds to 44 seconds, and makes a full kernel build enormously slower too.

This is on a 32-core (64-thread) AMD Ryzen Threadripper 3970X, fwiw.

This from Linus Torvalds. As the author of the Phoronix article notes, Linus is still “rocking” a Ryzen Threadripper system from four-going-on-five years ago, something the author finds surprising. I don’t think it’s surprising at all. After the high cost of moving to new hardware, there’s the equally high cost of time invested in the system to get it work the way you are comfortable with. And finally, you get to know that system and how it’s supposed to work; when something doesn’t work quite right you instinctively know and can start looking for what’s wrong, which Linus did.

Anyway, the update is now on the system and everything works just fine as it did before (so far).
