[Bug 1558079] Re: cryptsetup tcryptOpen doesn't work anymore

[nahz66]

I also received the error message, but with 3.19.0-58-generic.  I'm unable to revert back to 3.19.0-51 because some of drivers don't work with it anymore.
 Required kernel crypto interface not available.
 Ensure you have algif_skcipher kernel module loaded.

Let me know if there are are logs I can provide.

Title:
  cryptsetup tcryptOpen doesn't work anymore

Status in cryptsetup package in Ubuntu:
  Confirmed
Status in linux package in Ubuntu:
  Invalid

Bug description:
  I'm using cryptsetup to open TrueCrypt encrypted NTFS filesystems:
  cryptsetup tcryptOpen /dev/sdf2 tcrypt

  At least until linux-image-3.13.0-79-generic this work fine. 
  Booting linux-image-3.13.0-83-generic and running cryptsetup results in:

  Required kernel crypto interface not available.
  Ensure you have algif_skcipher kernel module loaded.

  The module algif_skcipher is loaded, so the tenor of the error message
  is wrong, but cryptsetup cannot open the container, so at least there
  _is_ some error. Probably it's related to some unsupported instruction
  set. With  linux-image-3.13.0-83 there are errors in dmesg which are
  not present with linux-image-3.13.0-79:

  AVX instructions are not detected
