      I had to rescue my Debianized Linkstation from a similar fate a
      couple of years ago. I fixed the OS by booting on a different drive
      with a "virgin" OS image, then used it to repair my Debian OS that I
      connected to the Linkstation via USB connection.

      I think your first step is to figure out why your LS isn't booting
      on a "fresh" drive image. How are you running the 2.6 kernel? Are
      you using uboot or the loader.o kernel module?

      If you are just doing loader.o, then it should boot a fresh "virgin"
      image just fine. Maybe you need to disclose exactly what you have
      done so we can help troubleshoot it for you.

      If you are using uboot, then the drive needs to be prepared to be
      the way uboot would expect it. I'm not up-to-speed on uboot, but
      hopefully it doesn't expect the kernel to be at specific physical
      drive sector locations like many boot loaders do! This kernel
      placement would be hard to duplicate, you'd probably then need to
      try to get a serial console going or worse yet: JTAG, in order to
      give uboot special instructions, assuming that could even work!
      Then again, I don't know uboot-on-Linkstation (yet), and am assuming
      you put the kernel on the hard drive instead of flash memory, which
      may not be correct. Try to find someone who know more about it.
