This bug was fixed in the package makedumpfile - 1:1.5.8-4ubuntu1
---------------
makedumpfile (1:1.5.8-4ubuntu1) wily; urgency=medium
* kdump-tools now make use of smaller initrd.img files created in
/var/lib/kdump. This avoid optential OOM when the size of the initrd.img
becomes larger (LP: #1496317). Implementation details are :
- New kernel hooks are added to create smaller initrd.img files when new
kernel packages are installed :
/etc/kernel/postrm.d/kdump-tools
/etc/kernel/postinst.d/kdump-tools
- kdump-config is responsible for the maintenance of symbolic links used
to point to the appropriate vmlinuz & initrd files. Link maintenance
is done at each boot by kdump-config. New links will point to the
files named after the running kernel.
- The KDUMP_KERNEL and KDUMP_INITRD configuration variables are now
now enabled and use the symbolic links :
/var/lib/kdump/vmlinuz
/var/lib/kdump/initrd.img
o kdump-config has been adapted to show the symbolic link
