AM4 Mobos used for Ryzen

Anon-E-moose,

I've tried an RX450 and an RX550. That's Polaris11 and Polaris12 respectively.
Both work in my Phenom II. Indeed, I migrated the kernel from the old box. The kernel has both sets of firmware built in.

Here's dmesg after

I wouldn't think it would be memory either, since it works as a module.

I have an rx550 I couldn't get it to work as builtin either, so that's why I've stuck with a module.

You have a few odd selections in your config but I wouldn't think it would cause problems. (stuff dealing with soc's)

You mentioned having an oops even as a module, was it generated by the video card? If so what was it,

Anon-E-moose,

Its in my dmesg linked above.

Sorry I missed the link to dmesg :oops:

(I did look for it, just overlooked it)

I would be tempted to turn the acpi enforce from lax to no. ETA. I used to run lax, but have it set to no at least since I've been running 5.11 series

This looks a little funny

@Hello NeddySeagoon,

I also have a Ryzen and a RX 550 for Polaris 11. I switched my system to buid-in last week.

Anon-E-moose,

I've tried turning off

Neddy, I think the real key was telling acpi to leave things alone, even if it's in it's "range".
I think there is a difference between lax and no, even though the kernel doc says they should be effectively the same.
I suppose that it could be just something that affects a minor kernel version or two, but I've never gotten ambitious enough to chase the problem down.

As far as the other options, they were probably ok, but when I get odd conflicts, especially reboots, oops, etc I tend to shut off options I know I don't need or add options that I might need.

I really need to go through my config and shut off options that are no longer relevant, I just got lazy because things are working well. :lol:

Anon-E-moose,

That was what bit me.

I copied the kernel .config from a Phenom II to a Zen3 and turned on the extra bits for the new motherboard.
That mostly worked :)

There is some junk there that I will get rid of as kernel updates happen.
That way, when, not if, I build a dud kernel, the last working kernel is there as a get out of jail free card.

Just built a new system with a MSI B-550A PRO. It wasn't clear that it needed a firmware update before it would recognize my 5600G processor, but once I sorted that it seems to work ok. Still to fully complete migration from Intel though.

Using 32G RAM in 4 sticks of 2400 MHz so I can re-use the 16G I already had.

There wasn't enough room on the screen for all the penguins until I adjusted the resolution!

While I am here a question about processor firmware. My processor appears to be series 25, whereas Linux a firmware stops at 23. Would there be any point in using version 23?

greyspoke,

AGESA is a part of the BIOS. It executes on the CPU like the rest of the BIOS.
The microcode is the hard wiring (it used to be hard wired) the tells the CPU how to execute each instruction.

There is a version of the microcode in slow permanent memory inside the CPU. This microcode in transferred to the microcode RAM inside the CPU for execution.
It executes at the full CPU core speed there.
As its in RAM, it can be updated.

The BIOS often contains a copy of a later microcode that that shipped inside the CPU, so the BIOS can update the microcode.
/lib/firmware/ can contain a later still version of the microcode, so the kernel can update it too.
The microcode updater does version checking. It won't load the wrong microcode for your CPU and it won't overwrite a new one with an old one.

Intel have recalled CPUs for a microcode error, in the days when it could not be updated.

Thanks Neddy, that makes sense of it for me.

Just wanted to mention the new AMD P-State driver in the 5.17 kernel seems to be working here. Can't say I've noticed any difference but I'm not looking very hard.

So, interesting problem showed up when I did a bios update (asus 1405 -> 4204)

After the update, system started, but for the next week, I spent many hours trying to figure out why it was unstable, spurious reboots, etc.

Among some of the things that the update "did for me" :roll:

was to leave garbage/bad values spread throughout the mem setting area,
most things were originally set auto, but the update set some strange values. Got that straightened out. Still unstable.

Mem is 3600Ghz and has reliable run at that for well over a year now, but I had to lower it to 3200 level to get the system to quit rebooting.

So playing around with some of the knobs in the bios and clicked on TPU tab, which allows 2 values TPU1/TPU2, one being air cooled oc, the other geared toward water cooling.

It set the speed to be 4050Ghz, which is a nice bump, by setting the CPU core ratio option (40.5 in this case) but I was still seeking stablility, so I set the value to 36 which corresponds to 3600Ghz which is the nominal rated speed. No problem. But in setting the value to 36 I noticed that that adjusted the voltage for things like VDDCR Cpu Voltage, left me at 1.105 volts. This got me to thinking, I know that my original setting for core ratio was auto, which gave me a running high 900 mv range, appx .1 to .2 off the voltage set when 36 was selected. But the system had been running fine this way for over a year, until the update.

So either amd is doing something different (asus and other use their reference) or asus is doing something different.

And since I'm running a slightly higher voltage, I notice the temps are slight higher (not surprising) but still well within tolerance (38 idle instead of 34)

Anyway, bottom line if you have stability problems after an update on your ryzen mb, you might check things like the cpu voltage.

Edit to add: These are the messages I started seeing (in linux) after the bios update (before I figured out what was going on)

I'm actually looking for a new AMD X570 based motherboard. Does anybody have a recommendation?

I had either the ASUS TUF Gaming X570 Pro WiFi II or the Gigabyte X570S Aero G in mind

- From what I figured neither of them has the annoying chipset fan that the X570 based models had (ASUS just doesn't seem to call them X570S motherboards?)
- Both of them have an Intel 2,5Gbps NIC onboard (essential for any stable network connection in my opinion)
- I don't care about the WiFi / Bluetooth that they offer (as I'll not be using it anyway; The ASUS motherboard has a Mediatek based chipset and the Gigabyte motherboard has a ADMTek based chipset)
- Both of them offer Realtek High Definition Audio (which is fine by me, as I'll be using my AudioQuest Dragonfly USB device)

Does anybody have any experience with either of these motherboards on Gentoo? How about sensor monitoring? I read that the Pro WiFi is supported, but I couldn't find anything anywhere about the Pro WiFi II (ASUS basically markets them as the same motherboard, as they even point to the same reviews on the website, while they're actually quite different). Couldn't find anybody that had any experience with Linux on either of these boards either.

Just wanted to add that things have improved with the P-State driver, happily using it nowadays.
