i have problems compiling my own kernel ...if i use the provided .config
it works if a add only one option kernel get to big....and stops
on boot ...............

but i also have devfs..prohlems.,.on booting ....root cant be loaded--
with kernel 2.6.7 it works....

?? i wonder why there is no .config with build in ...mol needed modules
and wirelles ...options..

but have to say problems always starts after emerging new portage and sync


thanx ;Maurix

What is the size of your vmlinux file ? You have to builtin a lot of stuff for
it to become too big i guess ?

devfs is obsolet, and will (or has) been removed in future 2.6 kernels. MAybe
it already got dropped in 2.6.10 ? Don't think so though.

mol modules are separate from the kernel sources, not sure if gentoo included
them, but i don't think that would be wise.

Hehe.

Try disabling stuff you don't need. In the default config all filesystems are enabled for instance, like XFS, ReiserFS, JFS etc. Disable the ones you don't need. I designed the default config so that it should work on as many systems as possible based on user feedback, so I pushed the size limit to get as many features as possible in there.
Also check the Device Drivers -> Graphics Support section, disable all graphics drivers that you don't need.
devfs has been deprecated as of Gentoo 2004.3. Disable devfs in your kernel config and 'emerge udev'. devfs should still work, but there is no point in debugging it since it will be dropped soon anyway.
After upgrading your kernel simply rerun "emerge mol alsa-driver x11-drm" to update the kernel modules of the respective packages.
Are you running on a 'ppc' or '~ppc' profile? 'ppc' means less hassle but older software. '~ppc' can give you an extra headache now and then but on the other hand you will always have up-to-date software.
On the other hand, I have not experienced any problems with '~ppc' recently so I would appreciate it if you report bugs to http://bugs.gentoo.org/ or here (the former method preferred).

well i tried to use your provided .config.
after boot i have:

gunzip...(0x000100<-0x00806c88:0x009f7359) inflate returned -5

i have set boot-memory to 0600000 already (

argggggggggggggg..............)
my 2.6.8 kernel works,,,,

upss forgot ,...kernel size is 2.8 MB

That means it is too big.
Change everything you do not require to boot into modules to reduce the size. (like audio drivers, file systems you do not need to boot etc). Let hald load modules on demand, or set them in /etc/modules.d/kernel-2.6
