I can reproduce winterfairy's results on a ThinkPad X201 (both with
the shutdown applet and with the emergency shutdown). FWIW, both this
system and the ThinkPenguin Royal have Intel graphics. I can't
reproduce this issue in libvirt/qemu (qxl graphics). winterfairy, what
graphics driver is used by the system exposing this bug? Can anyone
try and reproduce this on bare metal with non-Intel graphics?
I've seen no indication that the kernel has finished loading and run
the initramfs' init. I haven't checked if the memory wipe did happen
or not. I fear we have to treat this as a serious regression.

1. It could be worth having another look at the initramfs-tools
changes between 0.114 and 0.115. I would start with an ISO built
from experimental, that downgrades this package to 0.114.
2. It could be worth trying with kexec-tools 2.0.4-1 from sid and with
2.0.3-1 from Wheezy.
3. Any changes to the kexec feature in the kernel that break it for
our usecase?
4. kexec-tools didn't change since 0.21 so it can't be it.
winterfairy, do you think you can take care of any of this in the next
few days (say, before next Tuesday)? If not, anyone else?
(We'll verify #0 while running our test suite against the RC on Sunday
anyway, but if we could have more information or even a fix earlier,
it would be even better.)
Cheers,
