Sounds like missing drivers. oldconfig didn't do everything it was
supposed to. Moving across multiple major versions, this is to be
expected. A lot of names of things have changed.
Do a comparison of your configuration between old and new.
diff -uN old-config-file /usr/src/linux/.config
Make sure to at least enable NVME with CONFIG_BLK_DEV_NVME=y and try
booting 5.7 again. Other than that, the naming scheme may have changed
but I don't know about this. For better future-proofing, use a UUID of
your root partition rather than a device name.
root=UUID=...
You can get this UUID with the blkid command.
