Hmm. No, that version looks okay.

What's the kernel message log? Does it say something about 'dev_loss_tmo' ?

If so, can you try with 'export nvme_trtype=tcp' and then running the 
tests? Previous versions of nvme-cli had issues with nvme-loop, and were 
trying to set the 'dev_loss_tmo' parameter, which isn't valid for loop.

Cheers,

Hannes
