element432,
Post your grub.cfg please. I'm fairly convinced its not finding the root filesystem when its connected to the lab PCs

element432,
The filesystem UUID is supposed to be unique.
| Code: | | root=UUID=b1dc361f-3909-4f66-87b4-6f1cc0c77db9 |
so thats good.
Using root=/dev/... can lead to confusion.
I don't see either rootwait or rootdelay there.
Try rootwait and see if it waits forever.
If that stops the panic, even though it doesn't boot, we know that the root filesystem never appears.

| It just kills me that I can't get it to boot here haha. I've used a persistent Kali USB and an Arch install on a USB and they had no problems. |

| So I tried to boot with rootdelay, with no success. Then I decided I would just try to make a kernel quick with make localyesconfig to see if maybe it was the initrd causing problems. So I booted with the live dvd, and tried with the minimal-cd. Both, when chrooting, gave me the error: illegal instruction, for chroot /mnt/gentoo /bin/bash. I did try to use systemrescue cd, but I couldn't actually get that to even boot. |

element432,
What are your CFLAGS set to?
Post output.

element432,
Ahhh ...
| Code: | | CFLAGS="-march=native |
that built your USB install to run on the CPU that did the building. It will therefore only run on instruction set compatible CPUs.
Run anywhere distros, like binary distros, SystemRescueCD, the Gentoo liveCD and stage3 are built with
| Code: | | CFLAGS="-mtune=generic" |
and -march unset.
You can ask gcc what "-march=native actually means. | Code: | | gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )|( -mno-[^\ ]+)//g' |
My AMD system shows
| Code: | $ gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )|( -mno-[^\ ]+)//g'
-march=amdfam10 -mmmx -m3dnow -msse -msse2 -msse3 -msse4a -mcx16 -msahf -mpopcnt -mabm -mlzcnt -mprfchw -mfxsr --param l1-cache-size=64 --param l1-cache-line-size=64 --param l2-cache-size=512 -mtune=amdfam10 |
The 64 bit Raspberry Pi says | Code: | | -mlittle-endian -mabi=lp64 -march=armv8-a+crc |
and my Intel server says | Code: | | -march=ivybridge -mmmx -msse -msse2 -msse3 -mssse3 -mcx16 -msahf -maes -mpclmul -mpopcnt -mavx -msse4.2 -msse4.1 -mrdrnd -mf16c -mfsgsbase -mfxsr -mxsave -mxsaveopt --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=8192 -mtune=ivybridge -fstack-check |

| Haha, once you asked for that, I instantly thought, "I probably shouldn't have basically of copied my laptops make.conf. I'm going to change that and see what happens. |

element432,
You changed the spec. That's scope creep. :)
You will need to rebuild everything to be safe. If grub runs, you are just lucky.
Also revisit your
That need not be empty as all 64 bit CPUs had some CPU_FLAGS_X86 in common,
Use whatever the stage3 uses.

| So, when you say rebuild everything, you mean emerge -e world? |

Edit - I left the CPU_FLAGS_X86 out, with the other use flags to save some room. |
