** Description changed:

  Ubuntu 10.04 on a NetPC, after a synaptic upgrade that installed kernels:
  2.6.32-23-generic
  2.6.32-24-generic
  I got always this error on boot:
  [ 1.148845] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)..
  The same happen booting in recovery mode.
  
  Everything work as expected with the old one:
