It is recommended that all Gentoo Linux users upgrade their kernels.

If you are running any of gentoo-sources, gs-sources, pfeifer-sources
sparc-sources or xfs-sources updates are available. Sync your tree and 
run emerge  to install the latest version of the package. Then
compile and install your new kernel and reboot.

If you are using an other kernel package which hasn't been updated or 
download your own sources you can download a patch from
and manually patch your kernel.
