After the boot crash that I had, eventhough I choose 2.6.28-hostmode1 in the multiboot menu, after the uname -a command, the output is 2.6.28-kernelpower40. So I booted on the kernel 2.6.28-omap1 and just reinstalled the 3 kernel package you provided in the correct order. Then I could boot the 2.6.28-hostmode1 kernel. And Finally Thanks a lot for the job achieved ! It is awesome ! Nerfiaux
