Different issue? Maybe caused by the same regression?

After some more testing on the ISO I had, I too believes it is caused by
the kernel upgrade. But I do not think it is the kernel's fault.
When it reboots even though I selected shutdown, it actually does not
reboot properly. It reboot early in the memory erasing procedure (possibly
in the beginning) and leaves the memory unerased.
This makes me believe the memory erasing acts badly with this kernel
version and hardware combination, possibly writing some data somewhere it
shouldn't had, causing the kernel or hardware to force a reboot. And that
it worked with previous kernel versions on this hardware by pure luck.
I want to look deeper into this, but I cannot find where the actual memory
erasing code is (where sdmem is started?)? Only where the kexec bits are.
Where is it?
