Aborting...Hey everybody. I've been learning how to compile my own kernel lately, and things were going well til now. I have no idea what is causing this... I am making changes to the configuration of the kernel, so maybe its something I changed, but I'm really not sure what exactly it could be. Any ideas what might be the culprit behind this error? I'm using the archlinux default config with linux-xanmod on the AUR, enabling things like F2FS, XFS, deadline as default, adding drivers like r8169, btusb, usbhid, k10temp, fam15h, nvidia_fb, ahci, xhci, ohci, ehci, enabling some AMD-specific stuff, etc.Also, what are the best advantages I can get out of building my own kernel? What are some good do's and do-not's?
