27 SOLUTION
28
29 It is recommended that all Gentoo Linux users upgrade their kernels.
30
31 If you are running any of gentoo-sources, gs-sources, pfeifer-sources
32 sparc-sources or xfs-sources updates are available. Sync your tree and
33 run emerge <package> to install the latest version of the package. Then
34 compile and install your new kernel and reboot.
35
36 If you are using an other kernel package which hasn't been updated or
37 download your own sources you can download a patch from
38 http://cvs.gentoo.org/~aliz/linux-2.4.20-ptrace.patch
39 and manually patch your kernel.
