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.
