Compiling a custom kernel.

Hey there

I wanted to compile my own kernel for my new gentoo install. But after have selected what parts I want in the kernel and genkernel starts to do its stuff i get this error in make bzImage:
make[2]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r5/net'
make[1]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r5/net'

What does that mean and is there anything I can do about it at all ?
I'm trying to compile the kernel I got but running emerge gentoo-source and it gave me:
linux-2.4.20-gentoo-r5
I have tried with the r6, but I get the same error.

I would really apreciate any help and if you need any extra information I will get it for you.

Gentoo-sources are highly optimized ... too high for some combinations. Try vanilla-sources (unless you really depend on some patches)

If the error occurs with vanilla-sources you might have hardware problems (overclocked? too hot?)

I didn't know the Gentoo sources was so optimized.

I don't really depend on any patches from the gentoo-sources. But I wouldn't mind some optimization's.

I compiled the gentoo-source default config when I installed Gentoo 1.4, so I just wonder why it won't work with a non-default .config.

My machine isn't overclocked since I would not get any real performance increase going from 2.4 ghz to 3.2 ghz (loose comparison with 5 block's of SETI-data).
The machine is watercooled and running at 40 degres celcious full load for a few days.

I really don't think that this is a gentoo-sources optimization issue. It seems like you CPU is too hot or something...
But if it's water cooled, then it can be something else.

Try to make your kernel by hand, not using genkernel. (Post again if U need help, or take a look on other posts).

See ya!

I'm with cleber, do it the old fashion way. You're running gentoo for god sake.
