When I build kernel with gcc 3.4.6 everything works fine.

gcc-3.4 -v
Reading specs from /usr/local/bin/../lib/gcc/i686-pc-linux-gnu/3.4.6/specs
Configured with: ./configure --prefix=/usr/local/ --disable-nls --enable-shared --enable-languages=c --program-suffix=-3.4
Thread model: posix
gcc version 3.4.6

gcc -v
Using built-in specs.
Target: i386-redhat-linux
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-libgcj-multifile --enable-languages=c,c++,objc,obj-c++,java,fortran,ada --enable-java-awt=gtk --disable-dssi --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --with-cpu=generic --host=i386-redhat-linux
Thread model: posix
gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)

Here is a config file http://www.stardust.webpages.pl/files/mm/2.6.18-rc4-mm2/mm-config
