-When working with Linux kernels, the GNU C Library version from
-version 2.4 on is intended primarily for use with Linux kernel version
-2.6.0 and later. We only support using the NPTL implementation of
-pthreads, which is now the default configuration. Most of the C
-library will continue to work on older Linux kernels and many programs
-will not require a 2.6 kernel to run correctly. However, pthreads and
-related functionality will not work at all on old kernels and we do
-not recommend using glibc 2.4 with any Linux kernel prior to 2.6.
-
-All Linux kernel versions prior to 2.6.16 are known to have some bugs that
-may cause some of the tests related to pthreads in "make check" to fail.
-If you see such problems, please try the test suite on the most recent
-Linux kernel version that you can use, before pursuing those bugs further.
+When working with Linux kernels, this version of the GNU C Library
+requires Linux kernel version 3.2 or later.
Also note that the shared version of the libgcc_s library must be
installed for the pthread library to work correctly.
-The old LinuxThreads add-on implementation of pthreads for older Linux
-kernels is no longer supported, and we are not distributing it with this
-release. Someone has volunteered to revive its maintenance unofficially
-for at least a short time for the benefit of those using Linux kernels
-older than 2.6, but a working version is not presently available. When
-it is in working condition, we will make it available alongside future
-glibc releases. LinuxThreads will not be supported.

-The code for other CPU configurations supported by volunteers outside of
-the core glibc maintenance effort is contained in the separate `ports'
-add-on. You can find glibc-ports-VERSION distributed separately in the
-same place where you got the main glibc distribution files.
-Currently these configurations are known to work using the `ports' add-on:
-
- alpha*-*-linux-gnu Requires Linux 2.6.9 for NPTL
- arm-*-linux-gnu Requires Linux 2.6.15 for NPTL, no SMP support
- arm-*-linux-gnueabi Requires Linux 2.6.16-rc1 for NPTL, no SMP
- mips-*-linux-gnu Requires Linux 2.6.12 for NPTL
- mips64-*-linux-gnu Requires Linux 2.6.12 for NPTL
-
-The ports distribution also contains code for other configurations that
-do not work or have not been maintained recently, but will be of use to
-anyone trying to make a new configuration work. If you are interested
-in doing a port, please contact the glibc maintainers; see
-http://www.gnu.org/software/libc/ for more information.

the manual in the current development sources to see if your problem has
already been corrected.
