Subject: Regression in 4.7-rc7

Hi,

Updated the laptop to -rc7 this morning, and it fails to boot. After 
bisecting it, this is the culprit:

     ACPICA: Namespace: Fix namespace/interpreter lock ordering

     There is a lock order issue in acpi_load_tables(). The namespace lock
     is held before holding the interpreter lock.

The last I see is grub loading initramfs, after that nothing. Very 
reproducible. Laptop is a Dell XPS 13.
