 |
|
I've recently successfully installed Gentoo and have my Gnome desktop all set up. I noticed that I was still using gentoo-kernel-bin rather than gentoo-kernel.
My first step was to unmask gentoo-kernel based on an older post to this forum by using the following command:
| Code: | | emerge --deselect gentoo-kernel-bin |
Next I commenced building gentoo-kernel with:
| Code: | | emerge -av gentoo-kernel |
I then ran eselect kernel to choose the correct one. Unfortunately, the machine reboots to the error "failed to mount /boot/efi unknown filesystem type 'vfat'."
I was able to successfully boot the system again by reverting to gentoo-kernel-bin. I then added a file named "vfat.config" to the /etc/kernel/config.d directory with the following contents and repeated the emerge/build process:
| Code: | CONFIG_FAT_FS=m
CONFIG_VFAT_FS=m
|
For what it's worth, I also tried this file with "y" instead of "m" and it made no difference. I still reboot to the failure to mount /boot/efi error.
What is the correct way to do this? Thanks! |

No output, vfat is also missing from cat /proc/filesystems output. A fresh install with gentoo-kernel and no gentoo-kernel-bin whatsoever encounters this same issue.
This is perhaps related to:
| Code: |
module: x86/modules: invalid relocation target, existing value is nonzero for type 1... |

This is the root cause the module is not being loaded.
| Code: | | find /usr/lib/modules/<kernel version> -iname '*vfat*.ko*' |
