What is the total RAM size on the system? please share the proc/device-tree info (sys.dts) on the system it failed $ dtc -I fs /proc/device-tree -O dts -o sys.dts Thanks Hari -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1746299 Title: update makedumpfile tool version to v1.6.3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1746299/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
