Hi. We updated the files in ( MdeModulePkg\Bus\Pci\NvmExpressDxe\ and other related folders) from stable version 202008 to 202411 (latest). We have attached the logs for successful booting (with Advantech Gen3 storage) &  an unsuccessful hang (with Western Digital Gen4 storage). Again, in the unsuccessful case, we see "NvmExpressPassThru: Timeout occurs for an NVMe command." Has someone seen errors like this before? How can we correct this error? Thanks, cheers! -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
