So my first attempts to replicate have failed.

Can you confirm the sha of your kernel build? If its has some none upstream patches can you provide the sha your kernel is based on.

My testing so far were based on bebc6082da0a9f5d47a1ea2edc099bf671058bd4


Can you also send me your kernel config so I can better replicate your build
