recompiled kernel, now it won't boot

[rjm]

Hi,

I'm trying to get alsa working, and i've just recompiled the kernel with sound support as a module. I copied the old bzImage to bzImage.orig and the new image to the /boot partition and rebooted, and I got this:

loading gentoo..........................

uncompressing linux...

invalid compressed format (err=1)

--System halted.

so I copied the old image back, but I get the same thing. Does anyone know the problem? I can't think what else i've changed. btw i'm using lilo to boot with atm.

ok forget it, don't know what i did but it boots fine now.
