Hi Riccardo, Are you sure it hangs? Or maybe console is going to a different output? Do these systems have a framebuffer installed? Linux might favor output there. What cmdline are you using for the kernels in grub?

So machine is "alive". Just for double-check I rebooted the 6.16 kernel and it still spits out crap.
