I finally got Gentoo installed and using the plain console after editing and uncommenting the single line for text console. Note that there is no longer any for grub, it appears it needs that line uncommented out as it worked exactly as I wanted.
What it did on the reboot, no menu showed up and automatically started with the framebuffer enabled and everything was in the top left corner of the screen (small but readable) and I'm not sure how to fix it.
What I suspect I need to do is simply look at and see if something changed settings on me but I didn't run | Code: | | grub-mkcfg -o /boot/grub/grub.cfg |
so what's going on.
Rebooted and got a VFS Kernel Panic with unkown block 8:114? WTF I'm assuming this indicates that it's drive 8 and partition 114, which of course does not exist so Grub is halucinating just like ChatGPT an all the other AI
I May be able to fix it but I'm only going to give it one try before I nuke grub from orbit and switch to ReFind as it doesn't throw the kernel panics unless it actually has an issue. It sure as frog isn't a special snowflake like grub is.

FastTurtle,
in major device 8, minor device 114.
Reading /usr/src/linux/Documentation/admin-guide/devices.txt
| Code: | 8 block SCSI disk devices (0-15)
0 = /dev/sda First SCSI disk whole disk
16 = /dev/sdb Second SCSI disk whole disk
32 = /dev/sdc Third SCSI disk whole disk
...
240 = /dev/sdp Sixteenth SCSI disk whole disk
Partitions are handled in the same way as for IDE
disks (see major number 3) except that the limit on
partitions is 15. |
so the kernel is being told to use a SCSI device for root.
It's left as an exercise for the reader to decode 114 to a drive and partition.
Grub has done its thing and loaded a kernel but not it seems not an initrd, or you should have been dropped to to a initrd provided shell to do some diagnostics.

| Both GRUB and Refind are able to pass invalid options to the kernel, leading to a kernel panic. Were you expecting an initramfs to handle mounting root? Were you expecting the kernel to receive a valid root= line? What root= line did GRUB give it? |
