    There is one more place except the r8169 driver where gcc 2.95.3 is bad.
    To reproduce the problem:

    (you will need HJL Binutils >= 2.14.90.0.8 and gcc 3.3.x)

    Check out a known good glibc from CVS:

    cvs -z 3 -d :pserver:anoncvs@sources.redhat.com:/cvs/glibc \
         export -d glibc-2.3.4-20040510 -D "14:45:00 2004-05-10 UTC" libc
    sed -i -e "s/stable/2004-05-10/" -e "s/2\.3\.3/2.3.4/" \
         glibc-2.3.4-20040510/version.h

    Alternatively, there is a tarball available (created with these
    instructions) which you can download from the following location:
    ftp://gaosu.rave.org/pub/linux/lfs/packages/conglomeration/glibc-2.3.4-20040510.tar.bz2

    Build glibc:

    cd glibc-2.3.4-20040510
    mkdir ../glibc-build
    cd ../glibc-build
    ../glibc-2.3.4-20040510/configure --prefix=/usr \
         --disable-profile --enable-add-ons=nptl --with-tls \
         --without-cvs \
         --with-headers=/usr/src/linux/include
    make
    (we will not install anything)

    Back up the glibc-build directory for future reference, but don't remove
    it now.

    Issue the "make ckeck" command when running linux-2.6.6 compiled with
    gcc 3.3.3. If you get a failure, make a note of it and reissue the "make
    check" command.

    Once you know all failures, remove the glibc-build directory and restore
    it from the backup you made previously.

    Reboot into linux-2.6.6 compiled with gcc-2.95.3 published by Free
    Software Foundation. Redo the tests. You will notice several additional
    errors in NPTL testsuite. That's why I think that linux-2.6.6 should
    never be compiled with gcc-2.95.3.
