Subject: kdump failed to load: /sys/firmware/edd does not exist
Date: Thu, 22 Dec 2016 17:12:12 -0800	[thread overview]
Message-ID: <345de9dc-d728-2c5c-5634-2e70c4c6e030@gmail.com> (raw)

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

status=1/FAILURE)

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 
--append="MAC=60:eb:69:21:2c:00 ROOTFS=disk IMAGE_PENDING=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
