  Modified files:
    sys/gnu/fs/ext2fs    ext2_vfsops.c 
  Log:
  In ext2_mountfs(), check that the superblock size, SBSIZE,
  is aligned with the sectorsize value returned by GEOM, before
  doing a bread() of the superblock.
  This eliminates a panic when trying the following on an empty CD-ROM drive:
  mount_ext2fs /dev/acd0 /mnt
