Here's a bit more information about the defect. I discovered this
accidentally while testing out a -STABLE kernel built today. When I
booted the -STABLE kernel, it went and autoloaded the
old /boot/kernel/acpi.ko from the -RELEASE kernel, and the system would
boot as normal. However, if I broke to the loader prompt and loaded the
-STABLE kernel and its corresponding acpi.ko, the machine would fail to
boot (as above, with the memory segment not being detected).
Would this help anyone in filing a PR about the issue?
