 |
|
I had a fine setup with dm-crypt and btrfs with blake2 checksum but after a kernel upgrade the kernel stopped booting the system I don't understand why it complains not finding the root device as I have the FS, dm-crypt, nvme and blake2 support built in. And more, 5.4 detects my block device (but can't mount it lacking blake2 checksum support)
here's a screenshot of the kernel message: http://imgur.com/a/rTNbJPU
I tried a fresh install and I get the same issue. |

soratobuneko,
Several things from your image.
often hints that your block device hardware driver is missing.
You don't say where root is but the kernel can see nvme0n1 and its partitions.
If root is there, its not that.
| Code: | No filesystem could mount root, tried:
|
is significant.
You have an empty list there. That means there are no filesystems built into the kernel.
You need at least the root filesystem built in, or you need to use an initrd so that the root filesystem driver can be loaded before the real root filesystem is mounted.
Reinstalling is a bad habit you picked up form binary distros. It won't fix Gentoo.
