I was able to reproduce the issue with A311D classic Reform and the Taifast SSD from the Pocket on kernel 6.18. I am no longer able to reproduce the problem with kernel 6.19~rc6.
@Savasten @tomicdesu @G3M Could you try flashing a system image from this gitlab CI job and find out if you can then see /dev/nvme0n1 again?
I forward ported our patches to 6.19~rc6 today and built above system image which includes that kernel so that you have an easy time test-driving it.
