Hi, Yi, Chris,

I observed the same failure using kernel version v6.7-rc1. In my environment,
five test cases failed from nvme/041 to nvme/045. I enabled NVME_HOST_AUTH and
confirmed the failures go away.

My understanding is that the test cases newly require NVME_HOST_AUTH since
kernel v6.7. Now I'm preparing blktests patches to check that requirement [1].
Will post them after some more confirmations.
