I want to build a custom kernel under Ubuntu. I configured and built the new kernel. The new kernel hasn't initrd and comes from vanilla source. I build this new monolithic kernel only with drivers it needs.
When I try to boot the new kernel I'm stuck at the
mknod step. It tries to
mknod new devices like
/dev/vca4. It fails because the root partition is mounted read-only.
I think the problem is that I've lost something about my hardware. If I boot with the default Ubuntu kernel, I haven't got any problems. Could anyone help me to understand why this happens?
