Hi Al,
The current HEAD of acpi topic branch boot process stops right after:
EFI stub: Booting Linux Kernel... EFI stub: Using DTB from configuration table EFI stub: Exiting boot services and installing virtual address map... XhcClearBiosOwnership: called to clear BIOS ownership XhcClearBiosOwnership: called to clear BIOS ownership L3c Cache: 8MB
I've been testing the topic branch on one of the Mustangs in the Linaro Server lab. The firmware version is: version 1.1.0-rh-0.15 built at 14:20:32 on Mar 13 2015. Can I have your .config you are using for ACPI testing?
