Gentoo way of installing new kernel

Hi,

I have not had muck luck with Gentoo yet, I installed a new system and used vanilla-sources, forgot the devfs and recompiled, got complaints about skewed clock, so I then did an emerge unmerge sys-kernel/vanilla-sources, and removed traces from /usr/src/. When having recompiled the new kernel the last time, I mounted /boot, copied bzImage there, umounted and rebooted.

I know get the ugly message:

boot:
Loading Gentoo....................................
Uncompressing Linux...

invalid compressed format (err=1)

 -- System halted

I have compiled my own kernels a thousand times on other Linux distros, but this one seem to differ from what I'm used to. I would really appriciate if someone would tell me what I'm missing. I got another similar message yesterday (same stage, after recompiling) but then it said something about no datastream... *confused here*

Please help...
