Hi, I encountered kdump load failure problem at SLES12 SP1 and SLES12 SP2. The 'systemctl status kdump.service' returned: tpfe2 /var/log # systemctl status kdump.service kdump.service - Load kdump kernel on startup Loaded: loaded (/usr/lib/systemd/system/kdump.service; enabled) Active: failed (Result: exit-code) since Thu 2016-12-22 09:24:46 PST; 32min ago Process: 18982 ExecStart=/lib/kdump/load.sh (code=exited, status=1/FAILURE) Main PID: 18982 (code=exited, status=1/FAILURE) Dec 22 09:24:46 tpfe2 systemd[1]: kdump.service: main process exited, code=...RE Dec 22 09:24:46 tpfe2 systemd[1]: Failed to start Load kdump kernel on startup.

When I ran '/sbin/kexec -d -p ...', the only suspicious output line was: /sys/firmware/edd does not exist. The kexec cmdline is: # /sbin/kexec -d -p /boot/vmlinuz-3.12.62-60.64.8.2.20161026-nasa --append="MAC=60:eb:69:21:2c:00 ROOTFS=disk IMAGE_PENDING=0 IMAGE=pfe-160901 SLOT=1 console=ttyS0,38400n8 MONITOR_CONSOLE=yes intel_idle.max_cstate=1 processor.max_cstate=1 TRANSPORT=udpcast TTL=1 MCAST_RDV_ADDR=224.0.0.1 FLAMETHROWER_DIRECTORY_PORTBASE=9000 START_TIMEOUT=30 RECEIVE_TIMEOUT=5 elevator=deadline sysrq=yes reset_devices acpi_no_memhotplug cgroup_disable=memory irqpoll nr_cpus=1 root=kdump rootflags=bind rd.udev.children-max=8 disable_cpu_apicid=0 panic=1" --initrd=/boot/initrd-3.12.62-60.64.8.2.20161026-nasa-kdump Could someone advise what might have caused /sys/firmware/edd not created? The kexec-tools in SLES12 SP1 version is kexec-tools-2.0.5-17.2.x86_64 I looked at sles11sp4 systems, the directory did exist. Thanks in advance, Jay
