[ Upstream commit1231363aec] A system with more than one of these SSDs will only have one usable. The kernel fails to detect more than one nvme device due to duplicate cntlids. before: [ 9.395229] nvme 0000:01:00.0: platform quirk: setting simple suspend [ 9.395262] nvme nvme0: pci function 0000:01:00.0 [ 9.395282] nvme 0000:03:00.0: platform quirk: setting simple suspend [ 9.395305] nvme nvme1: pci function 0000:03:00.0 [ 9.409873] nvme nvme0: Duplicate cntlid 1 with nvme1, subsys nqn.2022-07.com.siliconmotion:nvm-subsystem-sn- , rejecting [ 9.409982] nvme nvme0: Removing after probe failure status: -22 [ 9.427487] nvme nvme1: allocated 64 MiB host memory buffer.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
