Hello, using v2.6.24-7284-g9ef9dc6 (plus some patches that shouldn't affect kbuild) I have problems with parallel building (make -j 3). Sometimes the build fails, the error isn't always the same. The last build resulted in: ...

The command to start the build was: make "ARCH=arm" "CROSS_COMPILE=arm-linux-" -j 3 uzImage uImage zImage Image Running that command once more worked without errors. I could reproduce that problem with current Linus' master (v2.6.24-7284-g9ef9dc6). I did: while delmake ns9xxx_defconfig && delmake -j 3 Image zImage uImage && delmake mrproper; do :; done with delmake being a wrapper script that does make "ARCH=arm" "CROSS_COMPILE=arm-linux-" "$@" after adding the toolchain to my PATH.
