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