 Posted: Fri May 16, 2025 1:07 pm Post subject: Cant boot kernel after installing Gentoo on Qualcomm Elite X |
 |
|
Hello there
I am installing Gentoo on my newly purchased Lenovo yoga slim 7x which is a Qualcomm Elite X PC and has kernel support.
Minimal install CD dint boot so I used Ubuntu 25.04 for Arm64. Chrooted installed Gentoo. However when I try to boot Gentoo I cant boot the Kernel. I am using dist kernel, and everything else went fine.
This is what Grub says:
| Code: |
EFI Stub: Decompressing Linux Kernel
EFI Stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path
EFI Stub: Measured initrd data into PCR 9
EFI Stub: Generating enpty DTB
EFI Stub: Exiting boot services
|
I dont have any other logs not sure how to proceed/debug.
Any help would be appreciated.
Thanks !! |

Ok I was able to boot into Gentoo kernel.
Somehow kernel-dist does not work. I was able to login after compiling kernel and using generated DTB.
Grub doesnt find the DTBs on its own either. I am sure I am doing something wrong. But thats a future problem, I atleast can boot. Installing GUI now. Fingers crossed. |

Sadly that's the case, I've had to patch it manually for grub-mkconfig to find it on mine.
And and the kernel-dist does work, just puts the dtbs in etc if i recall correctly, not in boot. |

Yup I used ARM 64 minimal boot image. But Ubuntu 25.04 has arm64 support. it booted without any issues and I could install from there.

Good to hear. I will figure grub out later. Also looks like Arm kernel is leaner and I could compile in 10 mins with -j10 or maybe its just a fast processor so not a big deal.
I installed KDE, would probably port over my sway set up someday but I am kinda liking KDE with tiling extension. I have a working system.
Working:
- Display
- GPU (Freedreno)
- Keyboard
- WIFI
Not Working:
- Sound
- Bluetooth ( sound on bluetooth works in Ubuntu)
- Battery indicator (Works on Ubuntu with firmware extract script)
- External Monitor
- camera |
