I suspect that PR 34186 could be the culprit. At least, this problem
seems to be either a problem with bad memory mappings, or a bad
ACPI/BIOS call. PR 34186 describes a problem where the msgbuf would be
mapped but only partly backed by actual memory, causing a reboot when
the boot messages walk out of it.
I'll integrate the patch in the PR, for amd64 too. Then we can see if
this was indeed (part of) the problem.
