It only affects newer kernels with the following patch: commit 9012a6de6b43146c934752a60d358c31dbad4368 Author: Kamal Heib <kh...@redhat.com> Date: Tue May 19 13:12:17 2020 -0400 [infiniband] IB/core: Fix potential NULL pointer dereference in pkey cache If a kernel ships with this patch, it needs the 1st patch. [Test Case] Boot the current 5.4 linux-azure kernel from focal-updates (5.4.0-48.52) on an Azure instance with a mlx4 device without RoCE support, the devices are wrongly ignored. The expected result is that those devices are created an available. [Regression Potential] A potential regression would only affect instances running the linux- azure 5.4 kernels with mlx4 devices.
