Wx9100 on Talos II

(1/4) > >>

rheaplex:
Heya all.

(Thank you to MPC7500 for previous help on this.)

I have a Talos II with a WX9100 graphics card installed, direct from RaptorCS. The graphics card displays PetitBoot perfectly every time, and then almost always fails to come back up for the main OS.

I have tried many different things to fix this:
- Different kernel arguments? Nothing seems to help.
- Different distro and kernel versions? Nothing reliable.
- Different kernel page size? I thought that 5.5 with 4k worked well, until it didn't. Otherwise there was no correlation.
- Try nomodest for late kms? Passed nomodeset to OS kernel, faster boot, can’t lsmod amdgpu though.
- Fast reset causing problems? https://wiki.raptorcs.com/wiki/Enabling_Navi_10_On_Fedora_31#Disabling_fast-reset Followed guide, no change.
- PCI needs resetting? https://wiki.raptorcs.com/wiki/File:Pcie_hot_reset.sh Ran script with 0000:03:00.01 as the argument (the AMDGPU lspci entry). It jammed after printing “Removing 0000:03:00.01…”.
- USB hub causing issues? Removed during boot, no change.
- Electrical power load issues on CPUs loading main OS? Changed to two separate wall sockets first r the power supplies, no change.
- Bad DP/HDMI connector? Changed converter and cable, no change.
- No access to firmware? Try amdgpu as module, or compiled in w/firmware in image. Rebuilt initramfs after it looked like it failed during install (the Fedora post-install script didn’t like the Petitboot version strung being hex rather than decimal), it doesn’t boot.

I notice that the PetitBoot amdgpu module size is different from the main OS one in my current setup. Other than that I've got nothing.  :'(

dmesg output is attached. The interesting part seems to be after "[drm] amdgpu kernel modesetting enabled."

System config also attached.

Can anyone suggest a known good distro/kernel/firmware version/configuration that I can test against? Or is there anything I'm doing obviously wrong?

Thank you.

MPC7500:
I would use the AST GPU till Petitboot and then switch to the amdgpu.

"The graphics card displays PetitBoot perfectly every time, and then almost always fails to come back up for the main OS."

If you switch OFF the main power and let the system go completely dead, does it boot differently (better) ?

ClassicHasClass:
Petitboot is almost certainly using an older kernel, too (which is usually the case).

What are your kernel boot arguments?

MPC7500:
If you're on Kernel 5.14+ you have to add amdgpu.aspm=0 to the Kernel commandline.
