NQN is supposed to be unique but some Intel drives do not follow that. [Fix] The device-supplied subnqn is ignored and one will be generated as if the field is empty. The upstream patch conflicts with a value in 'enum nvme_quirks' that we added in a SAUCE patch, changed that from (1<<8) to (1<<15). [Test] With this fix, both drives can be seen. [Regression Potential] The fix limits to Intel 760p/Pro 7600p SSD, and the fix has been verified by the bug reporter. --------- I bought a new Thinkpad X1 Extreme, and had it come with two SSDs, one 256G and the other 512G with the intention of keeping the windows on the 256G disk and using the 512G for linux. When dealing with the installer, it only ever saw one of the SSDs. I did manged to get bionic installed on the 512, but on boot, sometimes it doesn't find the 512G disk and I just get a blank screen. After a hard power-off, and reboot, it drops into the grub selector, and choosing linux, it failed again, but this time dropped into a VT.
