My disks are not showing

[riadkabir45]

Instead of compiling everything, I used apt download and dpg-deb to setup a initramfs.


But for some reasons i cant find my hard disk in /dev. Also blkid or proc/partition is empty. This happends when i use kernel from apt. Also I dont see any changes to dmesg when i plugin my usb mouse.

Now if i compile a kernel with defconfigure, everything is fine. I can find my disks and i see reaction to device plugin.

I think this is due to feature missing in that kernel. But i cant find what features cause this.

It sounds like a module is missing.
OR maybe kernel regression.

Does lsusb see any devices?

What kernel are you running?

its 5.11 from ubuntu hirsute
i tried debian kernel too
but also same

i also want to know if it needs module
how it mounts the root argument
as i see no modules in ubuntu initrd

The only thing that I can think of is go to the Linux Kernel Archives and read the changelog for kernel 5.11. That might help enlighten you.
