Hi!

I always got many "I/O error" messages when I use the program with "nokernelcrypto" parameter. The error is appears on Debian stable and Ubuntu system too. I tested it with many different computers and HDD-s. All the HDD has not contains any bad sectors.
I created a 25 Gb file container with AES-Twofish-Serpent encryption.
The error messages appears when i mount the volume.

Feb 6 13:38:33 localhost kernel: [ 2993.824886] EXT4-fs (loop1): mounted filesystem with ordered data mode. Opts: (null)

I got these error messages 200 times (with incremental sector numbers).

What is the problem?

Best wishes!
