Comment 17 for bug 499881

Alex,

Unfortunately, I compiled a Karmic kernel from our latest Karmic kernel fsl-imx51 branch. Then installed that kernel with my Lucid userspace. After testing the USB disk you gave to me, it is the same result as our latest Lucid kernel. It is failed to mount, since this:

Can you tell me which version Karmic kernel works when you test this?

Thanks,
