Hello there!
I have an HP Chromebook 11A and it doesn't want to boot, doesn't matter what I'm trying to do. It has an AMD A4-9120C on board. Let me explain the boot parameters with all the combinations I was using so far: * noacpi || acpi=strict * noapic * amdiommu=off || noiommu || iommu=soft * amdgpu.dc=0 || amdgpu.aspm=0 || amdgpu.gartsize=32 It turned out, there is something wrong with the AMDGPU kernel driver, because if I blacklist at the kernel parameters it works. Xubuntu 22.04 boots just fine. A very old Linux-LTS 5.4.17 version boots with amdgpu.dc=0, but that version doesn't have a working wireless device. Let me know, how can I help the debugging. I tried to use the console=ttyUSB option too, but the machine freezes before the pl2303 driver gets loaded. |
This task depends upon

Please follow the general advice for kernel troubleshooting [1]. It's not clear from your report if Arch is already installed.
You should first try to determine the last working kernel version. If Arch is not installed, you can find historical Arch isos here [2] which means you can then perform a kinda poor man's bisection.
Apart from that, some other things to try:
- boot latest -rc kernel to see if it works
- take it to the proper support channels (forum/IRC/etc) to seek help with debugging
- report it upstream [3]

So 5.10.90 was working also with the amdgpu.dc=0 parameter.
Now I hooked up a USB-C network adapter and I can see Arch running :)
I would say, the debugging part can be skipped as I can provide the logs already.
So as I mentioned Xubuntu 22.04 works, I assume there is something wrong with the Arch config.

" mb/google/kahlee: Increase VRAM from 16 to 32 MiB
While adequate for ChromeOS, 16MiB VRAM is insufficient for current
mainline Linux and Windows amdgpu drivers to operate properly. Under
Linux, the driver fails to allocate a framebuffer and causes multiple
kernel panics. Under Windows, the driver fails to load due to
insufficient resources available. Revert the VRAM allocation to the
previous amount of 32MiB."

My other idea was about the simpledrm kernel module. So I decided to build a kernel without that, but the Chromebook boots with the Arch packed packaged now.
I need to use amdgpu.dc=0 and iommu=soft now.
Thanks, we can close this issue!
