Description Peter Kien 2016-08-30 15:21:21 UTC 
I've been trying to boot the FreeBSD 11-RC2 memstick on my Lenovo
B590, but to no avail.

The system freezes during boot, ending with the following message:

---
acpi0: <LENOVO TP-H5> on motherboard
ACPI Error: No handler for Region  [ECOR] (0xfffff80003a33480) [EmbeddedControl] (20160527/evregion-180)

This issue is still exists, even with newer in-kernel ACPI subsystem.
