Hi gbittencourt, I have collected and uploaded the logs using the command you suggested.
The DMAR faults were observed while the OS was booting into the kdump kernel. I have also attached the kdump log for reference. Below are the DMAR errors observed during the kdump boot: From bnx2x driver: ================== [ 90.055556] DMAR: [DMA Read NO_PASID] Request device [23:00.1] fault addr 0xff6b8000 [fault reason 0x71] SM: Present bit in first-level paging entry is clear [ 90.269910] bnx2x: [bnx2x_issue_dmae_with_comp:563(ens2f1)]DMAE timeout!
