FWIW, I think this one is normal: the LVM metadata daemon isn't up yet at this early stage (I can observe that warning in my boot process too). > Volume group "hostname-vg" not found > Cannot process volume group hostname-vg Normal too: they will be there after cryptsetup unlocks things down there: > Please unlock sda3_crypt: # password inserted > WARNING: Failed to connect to lvmetad.

Given the intermittent nature, I'd lean towards flaky hardware (not necessarily the SSD). What happens if you try to boot from an external medium (e.g. a rescue system on a stick)? Ah, and while you are at it (and get your box to boot once more), make a backup :) Cheers - -- tomás -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlpt5HAACgkQBcgs9XrR2kb29wCfT7l80UBcO9mMQJeJd31w2F18 7OQAniAYtvGoz7FCa+zBahM/pqjMHJK9 =a2E1 -----END PGP SIGNATURE-----
