Intel P3600 writes after hot add (RHEL7.1)

[j cagle]

I'm having a problem with 2.5" Intel P3600 & P3700 Series NVMe drives
with RHEL7.1.

I can quiesce the drive, then hot-remove it, and there's no problem.

I can then hot-add it and it is discovered properly - no problem.

Then I can read from the drive, again - no problem.

The problem is that the server crashes (PCIe unrecoverable error) as
soon as I attempt to write anything to the drive:

[ 9838.102041] {1}[Hardware Error]: event severity: fatal

[ 9838.102062] Kernel panic - not syncing: Fatal hardware error!

Has anyone seen this error before?

Thanks,
