Hi James,

According to the resolution discussion here:

  https://downloadcenter.intel.com/download/28320/Known-Issue-Intel-SSD-760p-Pro-7600p-Series-SubNQN-Conflict-on-Linux

  "
  If you purchased your Intel? SSD from an OEM, your firmware version may
  have a different naming. Contact your local OEM representative for
  latest firmware revisions.
  "

Sounds like Lenovo will need to merge the Intel update into their
specific firmware if they haven't already done so.

Thansk,
Keith
