This is the first time ever that I ended up with an unbootable kernel

Here's the error I get at boot while the kernel is loading its device

I have ran into things like this before, I usually run make mrproper

laying around in there.
In my case, it was a fresh install, which made it quite a bit more
painful to fix because I had to go through the procedures twice and
For some reason, my SSH (openssh-4.5_p1-r1) refuses to remember any

Here's the verbose output when I try to connect to a known machine:

You probably moved your home directory using root, or something like that.
I don't remember doing that, but maybe I missed something during an

Crap! I totally forgot that I need ACPI support in the kernel for an

mini-studio using Linux. In Windoze, there's things like Cubase,

those does Gentoo have in the
