Hello there,
We have couple of Iron Lake machines here, and one started hanging around Christmas in early boot on ACPI initialization. Dmesg below, full dmesgs available on request.
Exact model of the machine is HP Compaq 8100 Elite Small Form Factor PC. BIOS update from 2010 to 2011 (newest) didn't change anything.
HP Elite laptop (ILK m540) or Dell SFF PC (ILK 650) don't have this particular problem.
I've bisected the problem to the following commit:
----
commit 174cc7187e6f088942c8e74daa7baff7b44b33c9
Author: Lv Zheng <lv.zheng@xxxxxxxxx>
Date: Wed Dec 14 15:04:25 2016 +0800
ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel
ACPICA commit cac6790954d4d752a083e6122220b8a22febcd07

The affected machine is a testhost and readily available for any patches that might help pinpoint this bug.
If you need any more information, you can contact me directly to this address.
Best regards,
