Comment 0 for bug 1797587

Every time you run an nvme format on a Intel NVMe drive (whether specifying the secure/crypto erase options or not), the format apparently works (drive is wiped clean) but the drive's admin queue (queue 0) times out, making the nvme device driver flag an error and reset the controller.

Here's an example:

nvme-cli-1.5 # ./nvme format -l 0 /dev/nvme1
NVME Admin command error:ABORT_REQ(7)
nvme-cli-1.5 # dmesg|tail -1
[79725.404910] nvme nvme1: I/O 151 QID 0 timeout, reset controller
