 1.) When I rebooted to install the new kernel the system managed to reboot
     despite the failed re-construction.
 
 2.) This is what I got when I attempted a re-construction with the
     new kernel:

 This time it actually seems to fail because of the LBA48 bug. I know
 remember that re-construct was done in the opposite direction in
 the past. I'll try to add the harddisk to the quick table.
 
        Kind regards
