cd /usr/src/
ls -all


does it show that that there is a symlink to to a valid kernel

for example mine shows:

bob@localhost /usr/src $ ls -all
total 16
drwxr-xr-x  3 root root   24 Apr 26 17:33 .
drwxr-xr-x 15 root root 4096 Apr 27 11:45 ..
-rw-r--r--  1 root root    0 Feb 14 00:03 .keep
lrwxrwxrwx  1 root root   22 Apr 26 17:33 linux -> linux-2.6.16-gentoo-r4
drwxr-xr-x 20 root root 4096 Apr 27 08:33 linux-2.6.16-gentoo-r4
bob@localhost /usr/src $

if the symlink isn't there then

ln -sfn linux-2.6.16-gentoo-r4 linux

obviously change the command to match your kernel version

if the symlink is there then check that you have .config in /usr/src/linux

if not then try copying it from /usr/src/linux-2.6.16-gentoo-r4

what does uname -a tell us. I believe you updated your kernel with the USE=symlink flag and may not have compiled your newly installed kernel and then rebooted and old kernel comes up but sources point to new uncompiled kernel.

[crashandburn0420]

localhost steven # uname -a
Linux localhost 2.6.14-gentoo-r2 #1 SMP PREEMPT Wed Dec 7 20:30:58 EST 2005 i686 Intel(R) Celeron(R) CPU 2.93GHz GNU/Linux

well as you can see that is the problem you have two possible solutions:

1) get your linux symlink to point towards your active kernel

ln -sfn linux-2.6.14-gentoo-r2


2) or compile your new kernel.
cd /usr/src/linux
make menuconfig
make && make modules_install && make install
reboot

if you're compiling your new kernel, copy your .config file from your old kernel:

[code]cd /usr/src
rm linux
ln -s linux-2.6.16-gentoo-r3 linux
cp linux-2.6.14-gentoo-r2/.config linux/.config
cd linux
make && make modules_install
cp arch/i386/boot/bzImage /boot/kernel-2.6.16-gentoo-r3[/copy]
then amend grub accordingly
sorry if that was a little patronising, i'm in that sort of mood

thank you that worked

no problem and if you want to avoid automatic symlinking of your kernel upon updates in the future just add -symlink to your USE in make.conf
