Additionally, the initramfs prompt does not accept any input, so I cannot investigate from there.
I have an older kernel (4.9*)) which still boots fine.
These things I tried so far:
- Used kernel param "rootdelay=10"
- Installed a newer kernel (4.19): fails the same way
- Compared the initrams of 4.13 and 4.9: the init script had some changes. Downgraded initramfs-tools from 132 to 130, now the initrams are same (according to diff on extracted files), but 4.13 still has that issue.
- The mentioned UUID c28..e99 is correct
Do you have any idea how to fix this?
*) Which I cannot use because compiling the NVIDIA module fails because of unknown rela relocation and I don't want to downgrade binutils (yet).
