Rocky 8.6 installs fine, Rocky 9 kernel panics

So I have an old Athlon 2 X2 quad core box, 32GB DDR3, MSI 970A-G43 mainboard, honestly don’t recall which but some generic Radeon board, Realtek chipset gig dual ehternet controllers, and WD 1TB spinning disk HDD.

Install of Rocky 8.6 goes smooth as butter, but installing 9 just won’t initialize, it gives me a kernel panic

I am assuming that something changed in the hardware support between 8 and 9, but just want to make sure.

I made a good solid mess of my 8 install and don’t want to spend the time cleaning it up so I am going with a fresh install…

Sorry I’ve been concentrating elsewhere. At what processor release is considered x86_64 v2?

Pretty sure it is a CPU issue, I would hate to have to retire this box early… And Ubuntu runs great on it…

Never mind, I have answered my own question. Found a nice awk script that checks version level of processors, looks like the OS has gone away from my hardware. Sad…

Early? Rocky 8 should last to May 2029. Not sure whether Ubuntu will run on it that long.

Back in the day as it were, one of the key advantages of using Linux was the fact you could keep older hardware going on it longer. So yeah early. I am not looking for the latest features, just to keep the old hardware chunking along enough to keep up enough with training lab requirements. This is far and away NOT production level stuff…

Even if you install successfully, there will be the following prompt
“Fatal glibc error: CPU does not support x86-64-v2”

No doubt. Which begs the next question. A quick google search for x86-64-v2 processor list shows a bunch of ways to test your existing processor, but no list of actual processors that meet this standard.

How would I know before buying and trying to install the OS on it what processors would be compatible if I wanted to upgrade my systems?

Are there any Socket AM3 processors that would work?

The x86-64-v2 means roughly Intel Nehalem and AMD Barcelona (or later), which did appear in 2008?

There has apparently been discussion in 2020 whether AVX2 should be a requirement and AMD did add that in 2015? That would have been quite a cut.

CPU Database | TechPowerUp lists AM3 CPUs (released 2009–2011) and the ones that I did check do not have SSE 4.2. Since they just seem to be a couple basic types (with many core/clock models), I’d guess none supports x86-64-v2.

As said, the non x86-64-v2 can be used at least to 2029. However, if you must run EL9, then you have to get a more recent system.

I don’t see the problem; with older hardware, just run 8.6, then when you upgrade hardware in a few weeks, do a clean install of 9.x.

It’s similar on Mac where certain hardware only supports certain o/s.

Update trainig, learning the new release so I don’t fall behind too far…

The 9 differs from 8 less than 7 does. The devil is naturally in the details, but if you master 8 and read the documentation of 9, then you should already be “close enough”.
