Comment(by bonefish):
Analyzing #1925 I encountered a general problem in the boot loader.
Physical address ranges between usable RAM ranges can later in the kernel
erroneously become allocatable memory (at least if they aren't claimed
during the VM setup). r34933 changes how physical pages are freed. Since
that revision they are enqueued at the front, so they are reused as
quickly as possible (thus being more cache friendly). For aforementioned
non-RAM ranges, that means they are likely already allocated during the
boot process, so that the negative effects can be observed earlier than
before (where that would only happen after a full cycle through the free
list).
I'm currently working on fixing the problem, but unexpectedly the actually
rather easy fix seems to cause the boot process to hang later (double
fault without entering KDL). Investigating...
