That was it. I used make clean and was able to compile. I feel guilty for not doing it before.
Thanks! 2 reasons why I don't use a snapshot. 1) When updating to the most recent snapshot, the installer doesn't seem to recognize the multi-core processor and uses bsd instead of bsd.mp. I then have to build GENERIC.MP and the rest of the cores are recognized. I'm multi-booting with REFIND (Linux & OpenBSD). I don't know if that may be the cause. 2) I wrote a driver that allows me to control the display backlight using wsconsctl. Building the kernel is the only way I know to add this driver.
