Title:
Creating bcache backing device using a Dell Ent NVMe CM6 MU 6.4TB

Status in linux package in Ubuntu:
Confirmed

Same error message is mentioned in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1909518, but the
suggested configuration change does not fix the issue:

Using a Dell Ent NVMe P5800x WI U.2 400GB storage works as expected:
