mkfs.ext4 hangs on trying to format a file system in an encrypted partition

srinidhih · ‎09-22-2021

Hello,
I'm trying to format a file system in an encrypted partition and my mkfs.ext4 command is stuck forever now.
I came across one of the old posts which suggested to reset the "CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API" config, (https://community.nxp.com/t5/i-MX-Processors/Hardware-accelerated-disk-encryption/m-p/281945) I did so and it did not help resolve my issue.

As the system gets hung on the above mentioned command I'll have to reset the board to recover it. Any suggestion in this regard is appreciated.

Output after executing the command:

root@aa:~# mkfs.ext4 /dev/mapper/00000000-0000-0000-0000-000000000000-etc
mke2fs 1.45.4 (23-Sep-2019)

Hello Yuri,
I followed the documentation and enabled the necessary kernel configs and installed the suggested tools. I am still facing the same problem.

Some of the outputs from my system are below.
