Mainline kernel 6.0+ hangs on S905D3

[Oleksii Fedorov]

Hello.

Sorry, it's been a long time since my last message, but I got back to checking this issue.
And I have found out, it seems is the issue with Arch Linux ARM kernel config file
https://github.com/archlinuxarm/PKGBUILDs/blob/master/core/linux-aarch64/config

6.3.3 kernel built with archlinuxarm config gives exact same issue

But if I rebuild same kernel but with Manjaro config
https://gitlab.manjaro.org/manjaro-arm/packages/core/linux-aml/-/blob/master/config
it works fine.

Any idea which kernel config parameter might be breaking boot on sm1 (khadas vim3l) board but work fine on g12a (radxa zero) board ?

Thanks.
