Installation of Debian bookworm (testing) on Lenovo IdeaPad 5G 14Q8X05

[Oliver Müller]

Hi,

the aforementioned ARM Notebook ships with the Qualcomm Snapdragon 8cx
Gen 1 aka SM8450, which was introduced in Linux Kernel 5.17. Firmware
for SM8450 is not included with firmware-qcom-soc (20210818-1) for bookworm.

Trying to install with a built thumb drive from
https://cdimage.debian.org/cdimage/weekly-builds/arm64/iso-dvd/debian-testing-arm64-DVD-1.iso
2022-09-19 03:34 3.7G booting the Kernel from the UEFI boot menu fails.
Making Grub a little more chatty by removing quiet from the boot options
I get a brief message:

'Booting a command list

EFI stub: Booting Linux Kernel...
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services...'

Followed by a reboot.

Am I under the right impression that the ISO ships with a Linux Kernel
5.19 that is compiled with SM8450 support?

Are there any activities with the vendor to provide you with the
firmware for SM8450 in the near future? Maybe benefit from Lenovo
ThinkPad X13s G1, Snapdragon 8cx Gen3 support in Linux Kernel 5.20.

Away from all that do you have any other suggestions to run the installer?

Thank you so much and have a nice weekend.

Best regards

Oliver
