2019-01-29 00:34:39 Michael Reed summary Unable to modify/create-namespace over NVDIMM-N [SRU] Unable to modify/create-namespace over NVDIMM-N
2019-01-29 00:40:26 Michael Reed description Steps to Reproduce: 1. Setup a Dell EMC 14G server R740xd server with NVDIMM-N, update BIOS & NVDIMM firmware to latest available to customers. 2. Install and boot to Ubuntu 18.04 3. Notice that no pmems are enumerated. 4. Try #ndctl create-namespace -> Failure with device or resource busy. Actual results: No pmems are enumerated, cannot create namespaces. If pmems are already present, then cannot modify the namespaces. Expected results: namespace creation should be possible Additional Info: * Seen with upstream linux-4.20.2 also. * Upstream bug report - https://github.com/pmem/ndctl/issues/78 * Upstream kernel patch: https://lists.01.org/pipermail/linux-nvdimm/2019-January/019435.html Request you to incorporate it in bionic and xenial kernels. [Impact] Users are unable to modify or create namespaces over NVDIMM-N [Test Case] Steps to Reproduce: 1. Setup a Dell EMC 14G server R740xd server with NVDIMM-N, update BIOS & NVDIMM firmware to latest available to customers. 2. Install and boot to Ubuntu 18.04 3. Notice that no pmems are enumerated. 4. Try #ndctl create-namespace -> Failure with device or resource busy. Actual results: No pmems are enumerated, cannot create namespaces. If pmems are already present, then cannot modify the namespaces. Expected results: namespace creation should be possible [Regression Potential] The Regression Risk is low, Intel not impacted but Dell is. [Other Info] Additional Info: * Seen with upstream linux-4.20.2 also. * Upstream bug report - https://github.com/pmem/ndctl/issues/78 * Upstream kernel patch: https://lists.01.org/pipermail/linux-nvdimm/2019-January/019435.html Request you to incorporate it in bionic and xenial kernels.
