I broke the kernel while trying to configure my sound driver. Didn't do anything strange. Just rebuilt the kernel. However, when I rebooted, I got a cryptic message displayed in dramatic red text:
pmap_bootstrap: no local apic!
I searched on Google and found links to cryptic C code. I didn't feel like wading through it. I vaguely remember it having to do something with pin mapping. I don't have anything of importance on the server yet, so I'm reinstalling everything... This is going to be a pain...
