["SOLVED"] cryptsetup luksOpen runs forever when using key file

I have a LUKS encrypted partition, that is unmounted
using an encrypted key file.

To open the partition i run:

gpg --decrypt KEYFILE | sudo cryptsetup luksOpen --key-file=- DEVICE NAME

After my last system update, which included new version of Linux, libgcrypt and
cryptsetup (new pkgver because of new version of libgcrypt) and a reboot, this
does not work anymore. Now `cryptsetup` runs at circa 100 % CPU usage forever.

For troubleshooting I have decrypted my key file and am running as root with
the same results:

cryptsetup luksOpen --key-file=DECRYPTED DEVICE NAME

I have verified that my key file is not corrupted and neither should the partition be
since it contains multiple backup superblocks and the disc only have two bad sectors
(as many as when it worked.)

Guess I should have made a smaller key file.
