Hi Louis,
I actually hit this bug on an openstack instance and it occurred to me what was happening. Its a fairly severe bug in our images, and I think it would be good to get the fix back to 12.04 at a minimum.
The issue occurs when the following sequence of events happen
* reboot issued
* system cleanly shuts down
* bios comes up, loads grub
* grub to do the 5 second countdown (see GRUB_TIMEOUT in
/etc/default/grub. The build scripts at [1] set this to 0 in quantal)
* grub writes that it started the kernel load to the grub environment
file /boot/grub/grubenv
* kernel starts running, and boot occurs
* HARD REBOOT HERE
* /etc/init.d/grub-common marks a "clean boot"
(this is run at S99 in via rc.sysvinit, very late in boot)
This bug 872244 is fixed in the cloud images in quantal.
Search for GRUB_RECORDFAIL_TIMEOUT in [1].
Also note, that this variable was added to grub at [2].
