After upgrading my machine. I rebooted, everything went as planned. So I decided to upgrade to a newer kernel. I was using: linux-3.10.7-gentoo-r1
and decided to switch to: linux-4.9.6-gentoo-r1 I've done kernel upgrade many, many times so it was a routine procedure. When I re-booted the last thing on the screen were letter: "GRUB" and blank screen, not even a kernel selection. I scramble, boot strap the system and copied two file in /boot/ kernel-old --> kernel-current System.map-old --> System.map-current I was under impression that something is wrong with the current (newest kernel). But it seems to me I run out of room on the /boot partition. ll -h /boot/ total 17M lrwxrwxrwx 1 root root 1 Dec 17 2011 boot -> . -rw-r--r-- 1 root root 109K Mar 5 10:20 config-current -rw-r--r-- 1 root root 90K Mar 5 10:13 config-old drwxr-xr-x 5 root root 1.0K Mar 5 11:48 grub -rw-r--r-- 1 root root 5.5M Mar 5 11:03 kernel-current -rw-r--r-- 1 root root 5.5M Mar 5 10:12 kernel-old drwx------ 2 root root 12K Dec 17 2011 lost+found -rw-r--r-- 1 root root 2.9M Mar 5 11:03 System.map-current -rw-r--r-- 1 root root 2.9M Mar 5 10:12 System.map-old df -h /dev/sda1 30M 29M 0 100% /boot When I installed the system I followed standard, installation instructions, and allocated disk space accordingly in Gentoo installation instruction manual. I think it wasn't enough. What I my options to reduce kernel size or increase /boot partition? Since I'm using VirtualBox the only module I'm rebuilding against kernel are: modules="vboxdrv vboxnetflt vboxnetadp vboxpci" + some Nvidia driver modules. But I've notice when new kernel was building where were a lot of other modules: "M" which I don't use I think. How to find them and disable them? Maybe it will reduce the kernel size. The current (linux-4.9.6-gentoo-r1) kernel size : -rw-r--r-- 1 root root 6.6M Mar 5 10:11 arch/x86/boot/bzImage -rw-r--r-- 1 root root 3.6M Mar 5 10:11 System.map I think when I copied the new kerenl size to /boot it didn't copied correctly as /boot run out of room. What are my other options? I'm using grub-0.97-r16 -- Thelma
