[Launchpad Bug Tracker]

You have been subscribed to a public bug by Ubuntu Foundations Team Bug Bot (crichton):

Based on upstream code commit explanation:

"""
On non-EFI systems, efi_info section of boot_params is zero filled resulting 
in an erroneous message from kexec regarding "efi memory descriptor" version.

Caused by commit: e1ffc9e9a0769e1f54185003102e9bec428b84e8 "Passing efi related 
data via setup_data"

# od -j 448 -N 32 -v -x /sys/kernel/boot_params/data 
0000700 0000 0000 0000 0000 0000 0000 0000 0000
0000720 0000 0000 0000 0000 0000 0000 0000 0000

# kexec -l --reuse-cmdline --initrd=/boot/initrd-`uname -r` /boot/vmlinuz-`uname -r`
efi memory descriptor version 0 is not supported!
"""

It was brought to my attention to some of our users are facing this:

----
## TRUSTY with kernel 4.4.0-83-generic

# /usr/sbin/kdump-config load
efi memory descriptor version 0 is not supported!
* loaded kdump kernel

/var/log/syslog:

Jul 18 13:37:06 xxxx kdump-config: /sbin/kexec -p --command-line="BOOT_IMAGE=/boot/vmlinuz-4.4.0-83-generic root=UUID=xxxxxxxx-20e4-4325-ad92-7aef2af0beac ro KDUMP_CMDLINE_APPEND=irqpoll maxcpus=1 nousb irqpoll maxcpus=1 nousb" --initrd=/boot/initrd.img-4.4.0-83-generic /boot/vmlinuz-4.4.0-83-generic
Jul 18 13:37:06 xxxx kdump-config: loaded kdump kernel
----

Despite the message of kdump being loaded, it doesn't look that it is
operational. Dump files could be generated using Xenial kdump-tools, but
not Trusty's.
