kdump failed to load: /sys/firmware/edd does not exist

[Jay Lan]

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

Hint: Some lines were ellipsized, use -l to show in full.

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

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
