AFAIK, rebuild the kernel should follow those steps at least:
- copy /boot/system-$(uname -r).map to ${kernel_src}
- copy /boot/config-$(uname -r) to ${kernel_src}
- cd ${kernel_src}
- make menuconfig, save config(If I don't wanna change anything for test).
- make -j9 bzImage.
- override /boot/vmlinuz-$(uname -r) with ${kernel_src}/arch/x86/boot/bzImage
Maybe those steps contains some typo or has some different paths. Buts the point is I don't change any features from original setting, I just copy my system.map and config to kernel source's one and rebuild the kernel(should be the same with mine).
When I override new kernel and reboot, It just hanged, no any message print out(No Oops, No panics). But if I do those steps with
this, everything goes fine. I just don't know the differences between the standard way and debian's way. Is ubuntu abnormal ?
