Hi,

I tried to build linaro kernel for pandaboard. I have tried everything what I can think of but the kernel still can't boot correctly. Any help will be appreciated. Here is what I did: 1. I flash the 13.07 linaro-ubuntu-pandaboard image into the sd card ( http://releases.linaro.org/13.07/ubuntu/panda). This image works fine. 2. I clone the kernel source code from git:// git.linaro.org/kernel/linux-linaro-stable.git. 3. checkout the lsk 13.07 tag. 4. copy the config file from original image (i.e. /boot/config-3.10.1.0-1-linaro-omap). 5. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- CFLAGS="-O" LOADADDR=0x80008000 uImage The cross compiler on my machine is gcc-4.7-arm-linux-gnueabihf-base 6. From pandaboard, I load the built uImage via scp.

The problem I met: 1. In most cases, the kernel can't boot correctly. And the terminal keeps printing "hub 1-1:1.0: hub_port_status failed (err = -71)". 2.Sometime, the kernel can finish booting. But the terminal prints for several times the aforementioned error message after booting. Plus, I don't have any module running, 'lsmod' shows nothing.

Please help! Thank you.
