I didn't know that removing a DVD was so simple.

I tried and the:

    error: AHCI transfer time out.

has disappeared!!!

All credits to Daniel Tarrero :-D many thanks Daniel!



Moreover, with Debian 8.2.0 installed, and before removing the DVD the
behaviour was:

but after removing DVD the behaviour was:

    grub> cryptomount -a
    Attempting to decrypt master key....
    Enter passphrase for ahci,msdos1 (d309etc...etc...etc...):

GRUB works for about 10 seconds then it prints:

    Slot 0 opened

whit no more:

    error: AHCI transfer time out.

Such error has disappeared!!!



The hang has disappeared after other commands too, running:

    grub> ls -la

GRUB instantaneously prints:

    Device memdisk: ...
    Device lvm/grubcrypt-swap: No known filesystem detected - ...
    Device lvm/grubcrypt-debian: Filesystem type ext* - ... UUID
      1cbd60e7-4b00-41cd-8220-944369022911 ...
    Device crypto0: No known filesystem detected - ...
    ...
    Device ahci0: No known filesystem detected - ...
      Partition ahci0,msdos1: No known filesystem detected - ...
    ...



RECAP

1. I have bought a Libreboot T400 with a HDD and a CD/DVD RW drive from
http://minifree.org/product/libreboot-t400/ It works perfectly with the
pre-installed Trisquel.

2. I have installed Debian with full disk encryption following Libreboot
documentation but I experimented some "error: AHCI transfer time out."
which last about 3 minutes. My "boot" process was:

  a. type LUKS passphrase at GRUB
  b. system hangs for about 3 minutes
  c. type (again) LUKS passphrase during debian boot
  d. type user passphrase at user login

3. I have removed the CD/DVD RW drive
(https://support.lenovo.com/es/es/videos/migr-72537) and the "error:
AHCI transfer time out." has disappeared. Now My "boot" process was:

  a. type LUKS passphrase at GRUB
  c. type (again) LUKS passphrase during debian boot
  d. type user passphrase at user login



Best regards,
Tarin
