Hi,
I have a problem with booting kernel built by buildroot on i486. The kernel (3.18.x) panicked: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
I use the latest buildroot, the target is i486. I used a kernel config from a known working older kernel and double checked, all ext2/ext3 etc. built directly to the kernel, so, seems every necessary drivers built directly to the kernel (not as modules).
I tried to boot from usb. There is no initramfs (initrd).
If I get a different kernel from an other system, which is working, and I started the buildroot generated system with that kernel, it can boot as expected. Same kernel parameters.
Does it sound familiar to somebody?
My goal is to get a console based system optimized to i486, including kernel.
What am I missing?
Thanks,
István
