Hello!

After using Gentoo for a few weeks, I decided to reinstall it with an encrypted root, using this guide. I think I have followed it to the letter(minus the partitions - I am using only 2 partitions, a 1GiB /boot partition and a root partition, all on a MBR partition table on a device with BIOS firmware), but when I exit the chroot environment and reboot, the GRUB menu shows up, I press enter on 'Gentoo GNU/Linux', a few lines print on the terminal, and the screen goes completely blank.

I think this may be caused by the kernel not building correctly, since upon running 'make install' in chroot, the following warning messages show:

Code:

Additionally, I am not sure why 'make install' tries to generate 'AMD CPU Microcode early initramfs image' - I have an intel cpu, not an AMD one. Also, while the first warning message says that the current kernel version is 6.6.32, running 'eselect kernel list' shows only 1 kernel, which is 'linux-6.10.0-gentoo'.

I am not sure what other information is necessary to debug this, but I will list some details that I think might be useful:

- In the rootfs encryption guide on the gentoo wiki, two methods of generating initramfs are detailed - either using UGRD or using Dracut. In this case, I am using UGRD.
- I am using the 'full manual approach' to kernel management
- I found a gentoo forum post that recommended enabling framebuffer support to fix a similar issue(I can't seem to re-find the exact post, but I think it linked to this section of the wiki). Following it, I enabled all 4 kernel config options listed:
Code:
<*>   VGA 16-color graphics support
 [*]   VESA VGA graphics support
 [*]   EFI-based Framebuffer Support
 <*>   Simple framebuffer support

- Apart from changes detailed by the installation handbook, dm_crypt wiki page, and all 4 early framebuffer options, I don't think I changed anything.

Sorry if I say something stupid or rude, english is not my first language. Thank you in advance for any and all help.

What GPU are you using? i know that nvidia cards have some particularities with which of the framebuffer options is selected.

iLag,

first of all: Welcome to Gentoo Forums ! :D

Code:
WARNING  | Kernel version is set to 6.10.0-gentoo, but the current kernel version is 6.6.32-gentoo-dist

tells me you have installed our distribution kernel AND gentoo-sources-6.10 ... maybe de-install one of them (*) ... and then check again your manually configured kernel with:
https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_Configuring_Kernel_Version_6.6#Part_3_-_Must_Haves
(Maybe you miss framebuffer console)

*) clean /usr/src/ and the softlink /usr/src/linux; but dont delete your distribution kernel in /boot, so you can boot it with grub if you need it

P.S.: Because you want 6.10 please read also:

Thank you for your response and for the welcome.

I was able to sidestep this issue since I made this post by using a distribution kernel instead of a manually-configured kernel, and modifying its configuration via this method. Unless I'm misremembering, I only changed configuration options that pertained to RootFS encryption - and not any of the framebuffer options.

My machine also doesn't seem to have the sys-kernel/gentoo-sources package anymore, only the virtual/dist-kernel package. I'm almost certain that, at the time of me making this post, I had only sys-kernel/gentoo-sources emerged - which is confusing, since I've no clue what exactly could have been causing this error to occur(As mentioned above, the distribution kernel didn't have any framebuffer configuration options changed, yet it worked without the error occurring). But since the distribution kernel is perfectly functional, maybe it isn't a problem anymore.

you should probably indicate that your problem is solved in the title of the post, for example by putting [resolved] in it (just edit the first post of the thread).
good to hear that you got your system working.

Happy Gentoo-ing!
