Problems during startup - UEFI Bootloader Kernel initramfs GPU

hatschiha · March 28, 2024, 1:47pm

I put a PC together like this:

AMD Ryzen 7600
ASROCK A620I Lightning
32 GB Trident Z5 DDR5 Ram
AMD Radeon 6600
500 W Powersupply
Intensio M.2 SSD PCIe

I put Opensuse Thumbleweed with KDE on it. Unfortunately very often it is not booting correctly. Without changing anything sometimes it goes:

In the emergency shell with dracut errors (like the NVMe could not be found, suggesting to rewrite the initramfs, I even found the UUID might be wrong)
The output is only on the mainboard HDMI-outlet without dedicated GPU support
The output is on the dedicated GPU but the GPU is not correctly recognized and 3D accelerattion is not working
Everything boots like intended (output via DP through the GPU)

I have no clue where to search. I studied Uefi setups. But there are so many options i do not understand. Finally I reset the CMOS with a jumper. After that everything worked until the system was rebooted two times.
I was trying to switch secure boot off. This send me on a very strange trip of mok keys and bluescreens and redscreens. I reset the CMOS to get back to start.
I put nomodeset as boot parameter. But then the graphic driver is not running at all.
I tried rootdelay=130 because sometimes the NVMe is not recognized during the boot process. I switched off fast boot in the UEFI BIOS. No change.

I can reboot from the bootloader if the graphical output is on the motherboard back to UEFI until suddenly the output is on the GPU. Sometimes everything is then running normal. Sometimes the GPU is not recognized.

I suspect it might be some Problem with the PCIe Bus. As the NVMe and the GPU are on the same connection.
The UEFI settings or the bootloader (grub2)?
Or is maybe the GPU damaged?
I need directions where to search for failures.

Hi schikkendidi! Nowadays assembling a PC from retail components is an easy exercise. But there are some pitfalls.

Carey Holzman has some nice videos, such as Build a Budget Friendly Long Lasting Computer!

For troubleshooting temporarily remove the graphics card and make sure your system works properly with the internal graphics. Only then put the card back.

jsmith64 · March 29, 2024, 6:26am

Karl is right. Remove your video card and try to get it stable. Do you have the proper power cables hooked up to the card with a capable power supply?

My NVMe has disappeared twice on Kernel 6.8.1.1. It crashed and when I rebooted it went to enter root password or Ctrl D to continue. I have to power it off/on to get it to boot. I believe it’s the kernel, it never did that before.

Also, I see you have BIOS 2.08 and there is a 2.10 available. It likely won’t help but you never know what they fixed.

You could have a defective GPU, it happens.
First go for stability without the card and if you get it stable enough, update the BIOS. Go through reboot, sleep, resume, reboot and see how it’s acting.

I forgot. Have you set your memory in BIOS to DOCP? It’s like Intel’s XMP profile but for AMD.

I don’t know what brand your PSU is but 500 watts is the minimum for a 6600 and many sites recommend 550-600. That may be a problem. If it’s a low quality PS then it’s likely a problem.

mrmazda · March 29, 2024, 6:47am

Does the Radeon have a separate power connector? If yes, is it connected?

Assuming previous isn’t applicable, either karlmistelberger’s suggestion, or 4 or more complete passes of a memory tester (e.g. memtest86 or memtest86+; in RAM testing, too much is just right, like HP in hot-rodding ), is the place to start, followed up by the other. You could go a bit further in reducing power required and remove all RAM except one stick. If you only have one stick, trade it for a pair of 16s, unless you’re certain you don’t have multi-channel RAM support. With a multi channel support motherboard, using only one stick (except for testing purposes) produces a monster performance penalty.

Given all the trouble seems to be evident in the first seconds or early minutes of a boot, I wonder if the PSU is the root problem, either instability, or not putting out enough of the advertised power to match system’s actual needs? 500W should be more than enough to cover your components’ needs.

Thank you for your highly appreciated replies.

@karlmistelberger the source of the videos of Carey Holzmann was unknown to me. thx
(- taking out the graphics card will be the next step.)

@jsmith64 I checked the cables over and over again. I noticed even a red light, when the additional power cable of the graphics card is not connected. But I am quite sure, that all cables are well connected including a satisfying “klick” sound.
I updated the BIOS to 2.10. I am fiddling with the problem since two weeks and when I started I updated already to 2.08 but did not notice the latest release.
If I managed to start the system with GPU support I started a few games for a couple of hours and everything was running stable.
The memory is “EXPO” ready and I tried it with and without the overclocking. I does not make any difference. The overclocking from 4800mhz to 6000mhz was done by a profile, which had already all values of timings and voltages correctly detected. I checked each setting with the makers product information.
I calculated the PSU with different websites. It is a SFX L from Bequiet. I should be more than enough power. The lowest advice calculated was only 350W the highest including spare capacity was 450W.

@mrmazda It is a good hint, but yes, all power cables are well connected including additional power supply for the graphics card.
I have two sticks of RAM. It is a dual channel kit.

After the BIOS/UEFI update to 2.10 the computer was booting on the mainboard output. But after I rebooted for TW updates the system started like intended.

I will go for some reboots, memory testing and for testing purposes replace the graphics card.

hatschiha · March 30, 2024, 5:25pm

So far the BIOS update to 2.10 did not bring any change. Still NVME missing or graphics card not detected on boot.
I made the memtest86+ two times without any failures. Will run it tonight for longer.
I took out the graphics card and booted for about 10x with reboot and complete shutdown. Never failed to boot up.
Tomorrow i will get a Nvidia 980 to see if the problem exists with this card as well.

malcolmlewis · March 30, 2024, 5:26pm

@hatschiha make sure fastboot is disabled in the BIOS as well…

hatschiha · March 31, 2024, 1:16pm

@malcolmlewis Yes, since i read, that the NVMe hiccup could be caused by booting up too fast i disabled fast boot. I left it this way ever since.

I am running now the NVIDIA 980 TI booted a dozen times. No problems at all. (I did not bother to install NVIDIA drivers)

I wonder what is wrong with this radeon 6600 and if it could be fixed. I read there is a vBIOS on the card. Is this automatically updated with the drivers on linux in general? Or should I try fiddling around with something like amdvbflash. Is there a tool, that can check the graphics card for errors? I mean if it is booting up sometimes it runs flawless until at some reboots it does not.

hatschiha · April 25, 2024, 6:54pm

Mystery is solved. It is a PCIe 4.0 motherboard and a PCIe 4.0 graphics card but there was a 3.0 riser in between. Switching the UEFI to 3.0 already fixed the problem.
So not software related at all.
