  The first case:  "/dev/sde1" Partition is marked as bios-grub and should not be trying to be mounted by kernel.
  The second case " /dev/sdf1" is used by truecrypt application . Kernel should not be trying to mount it.

  Thank You,

  P.S. Is it possible to tell to kernel not to trying mount some
  specific partition/s ? Like by some kernel parameter ...
