[SOLVED] Rx570 gives blank screen after fail to load firmware

Hello, i'm unable to boot because once the gpu gets the firmware i get a blank screen.

I have to use "nomodeset" to get to the LUKS password prompt as i can't get it without that parameter.

Error: amdgpu 0000:03:00.0: probe with driver amdgpu failed with error -22

I've posted into the amdgpu issues too: https://gitlab.freedesktop.org/drm/amd/-/issues/4474

Can't post on Arch issues because i forgot the OTP and i can't login, even if i emailed the support. Can't get in

Edit: SOLVED! It was a faulty HDMI cable

Re: [SOLVED] Rx570 gives blank screen after fail to load firmware

From your journal over there, there's actually no EINVAL after blacklisting and manually loading amdgpu, but

ago 07 20:08:21 Fantozzi kernel: amdgpu 0000:03:00.0: [drm] dce110_link_encoder_construct: Failed to get encoder_cap_info from VBIOS with error code 4!
ago 07 20:08:21 Fantozzi kernel: amdgpu 0000:03:00.0: [drm] dce110_link_encoder_construct: Failed to get encoder_cap_info from VBIOS with error code 4!

and then

ago 07 20:08:21 Fantozzi kernel: amdgpu 0000:03:00.0: [drm] Cannot find any crtc or sizes
ago 07 20:08:22 Fantozzi kernel: amdgpu 0000:05:00.0: [drm] Cannot find any crtc or sizes

the module thinks there's no output attached to either GPU - the late module load could just fudge some hdcp handshake.

* Have you tried to re-attach the output afterwards?
* Can you blindly enter the luks password and either ssh into the system or reboot by frenetically pressing ctrl+alt+del and then post the journal from the originally bad boot?
* Have/can you try Alex' patch at https://patchwork.freedesktop.org/patch/666266/ ?
* "amdgpu.runpm=0 amdgpu.bapm=0 amdgpu.aspm=0", https://wiki.archlinux.org/title/Kernel_parameters

Re: [SOLVED] Rx570 gives blank screen after fail to load firmware

* "amdgpu.runpm=0 amdgpu.bapm=0 amdgpu.aspm=0"

Results in blank screen

Will try other modes, but i had this problem even with the July Archlinux iso, i had to give nomodeset to install it. I think there's something in linux-firmware-amdgpu that's bad, i've tried the previous package with no results.

Bootlog of blind boot: https://0x0.st/KrzR.txt

I have a Rx550 too in the second PCIex 16x slot, but months ago i used that to achieve GPU Pass-through to a Windows 11 vm, but i could use both GPUs on Linux without problems, even on Windows i could use them - now that i think, i have virtualization disabled on BIOS, maybe the GPUs wants that to run in both... lemme check

detach and re-attach cable

Blank screen

Enabling virtualization support

Blank screen

In extremis, i see there's the August version of linux-firmware-amdgpu package in testing, trying to install that, let's see...

Edit: black screen, reverting to July firmware

Do you have another monitor?

No another monitor, but a Rx550 on the other PCIEx 16x (ATX mobo)

Just tried Fedora 42 Workstation live, it's from April, black screen when it changes mode.
No luck with the updated linux-firmware-amdgpu i upgraded before.

I don't know how to patch a driver, but i'm trying another HDMI cable.
