[brag + followup] configured and compiled a kernel for the first time ever 🛠️ Following the Arch wiki, I built a custom kernel for the first time ever. It was easier that I thought it’d be, probably because the Arch wiki is so thorough and because I didn’t make that many changes… I just enabled a few FireWire related options as per this guide in order to work on this project (or this). Results/takeaways The OS ran fine with the new kernel 💃 I learned how to manually create GRUB entries 🔧 I learned that I don’t even have to create new GRUB entries, since I can simply point to the new kernel image and initramfs from the bootloader menu 🪛 I learned that my 5800X3D runs well (compiles the new kernel blazingly fast) with all cores set to negative 30 in the UEFI FireWire is dead 💀 Tiny followup on that project That old GPU did something to the UEFI (possibly CMOS?), because even after removing all potentially incompatible hardware and reinstalling my modern GPU, I still got that same error message, saying that the system was forces to boot in CSM mode. Only by resetting the UEFI settings was I able to restore the system to a working state. I admit, I panicked.

    Congrats! Compiling your own kernel is very intimidating at the beginning and one learns a lot after plunging down that rabbit hole After some time it gets pretty straightforward. Just don’t forget to enable the modules for your drive and filesystem (it has been a while, maybe that’s not needed anymore) and the rest you can always fix with another compilation That part where you got stuck even after switching hardware: yikes. I wouldn’t expect that

    I’m playing with the idea of maybe compiling a custom kernel at some point, but it would mainly be to trim out stuff i don’t need to speed up compile time (i’m using gnu guix, and a few months ago the nonguix substitute servers were down for multiple weeks, causing me to have to compile the kernel myself everytime it got updated). I have a 5800X3D as well and it doesn’t take too long, about half an hour i think, but i still think it’s annoying if you have to do it regularly. On my laptop it takes like 1.5 hours lol. I’m not sure if it’s worth bothering with though, cause i’m also in the process of creating a guix config for my server and then setting up the server so that i can offload builds to it for my other systems (it uses a 3900x). Btw for how long have you had your 5800X3D? I think i’ve had it since 2021 or something like that, but i think the silicon is starting to degrade a little, cause this whole time i’ve also been running it with negative 30 offset, but i’ve been experiencing hard reboots these past months with errors in the logs indicating cpu-related errors. I’ve put the offset back on auto and it seems to be working fine so far, so i think it just might need a little more power to be stable.

    congrats! the arch wiki is awesome, isn’t it? also… this marks the second time this week I’ve heard of FireWire. though you might’ve had a better excuse for bringing it up. the other instance was my mother, mistakenly referring to the optical cable im running at home lol
