From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030611 Description of problem: The system's EFI memory map is not included in an ia64 kdump vmcore. This is evidenced by running the crash utility against it, where the following warning message is displayed during initialization: WARNING: EFI memory verification will not be performed Also, if during the crash session the "mach -m" command is attempted, it will fail like so: crash> mach -m mach: efi_mmap not accessible Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. run crash utility on ia64 kdump vmcore 2. run "mach -m" during crash session 3. Actual Results: Note "WARNING: EFI memory verification will not be performed" during invocation. During session, "mach -m" command fails with: "mach: efi_mmap not accessible" Expected Results: No initialization-time WARNING should be displayed, and the "mach -m" command should dump the contents of the EFI memory map. Additional info: The reason that this occurs is because the system's EFI memory map is not being copied to the kdump vmcore.
