I downloaded, configured and installed kernel downloaded from kernel.org. While booting up this new kernel for the first time, this error screen shows which is pointing towards a missing or wrongly mentioned root device probably. But I didn't mention it explicitly, installation scripts did it. So if this is the error, can someone please tell how to fix?
Or if the cause may be something else, please tell what it can be?
NOTE: I am using VirtualBox for all this process. Don't want my laptop to become unbootable for this experiment.
- Grub entries are fine, as it is same for another kernel running on this system and other kernel is working fine.
- DEVTMPS is just creating a warning, I think programmers care about errors only, not warnings, so hopefully this is not the major cause as well.
- TSC is giving an error, I investigated, it is probably a clock mode, nothing very related to root device.
- Again UUID is not an issue, because other working kernel grub entry is using same ID and booting up correctly.
