** Description changed:
+ [Impact] The kernel package no longer delivers the vmcoreinfo file so
+ the kdump functionality is now broken.
+
When using linux-image-3.2.0-6-generic and testing kernel dump
functionality, the kdump process fails.
This is caused by the following test in /etc/init.d/kdump :
-
KERNEL_IMAGE="/boot/vmlinuz-$KVER"
INITRD="/boot/initrd.img-$KVER"
VMCORE="/boot/vmcoreinfo-$KVER"
# Without makedumpfile, there will be no vmcore on crash, so no point
test -x /usr/bin/makedumpfile || exit 0
if [ ! -e "$VMCORE" -o ! -e "$KERNEL_IMAGE" -o ! -e "$INITRD" ]; then
- exit 0;
+ exit 0;
fi
The /boot/vmcoreinfo⁻{kernel version} is not shipped with the linux-
image-3.2.0-6-generic.
+ [Test Case]
+ While running a 12.04 Precise system, install the linux-crashdump package
that will enable the kdump functionality. Reboot the server then, as root,
issue the following :
+ $ echo c > /proc/sysrq-trigger
+
+ Normally, the kernel dump should be created in /var/crash. Currently the
+ kdump process fails silently and the system reboots.
+
+ [Regression Potential]
+ Upstream developer of makedumpfile which produces the vmcoreinfo file has
confirmed that vmcoreinfo is no longer required
(http://lists.infradead.org/pipermail/kexec/2012-June/006381.html). vmcore
generated with this patch have proven to be usable with the 'crash' tool.
