O.K. Thanks for testing that.

I Gregory

I have an older compile:

 arm-linux-gnueabi-gcc -v
Using built-in specs.
Target: arm-linux-gnueabi
Configured with: ../src/configure -v --with-pkgversion='Debian 4.4.5-8' --with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --program-suffix=-4.4 --enable-shared --enable-multiarch --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --with-gxx-include-dir=/usr/arm-linux-gnueabi/include/c++/4.4.5 --libdir=/usr/lib --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --disable-sjlj-exceptions --enable-checking=release --program-prefix=arm-linux-gnueabi- --includedir=/usr/arm-linux-gnueabi/include --build=i486-linux-gnu --host=i486-linux-gnu --target=arm-linux-gnueabi --with-headers=/usr/arm-linux-gnueabi/include --with-libs=/usr/arm-linux-gnueabi/lib
Thread model: posix
gcc version 4.4.5 (Debian 4.4.5-8) 

I'm using mvebu_defconfig and the only option i change is
CONFIG_INITRAMFS_SOURCE to point to my rootfs.cpio.gz file.

But of a long shot. Do you have much broadcast traffic in your
network? I just wonder if u-boot has left the ethernet interface
running, and during boot the hardware received a broadcast packet, DMAs
it into memory corrupting something? My board is on a very quiet
subnet, with virtually no broadcasts.
