--- Comment #1 from saunders.52@wright.edu --- There's a dmesg set on the Arch bug tracker provided for the power management failure case - Previous firmware revision: https://bugs.archlinux.org/task/53042?getfile=15004 Current firmware revision: https://bugs.archlinux.org/task/53042?getfile=15005
Looking at my Xorg logs over SSH at the time, there were no differences to a successful useage of Xorg on the previous firmware. I wasn't thoughtful enough to take a dmesg capture, and I've got a large workload running on my machine right now. I can probably experiment with getting the logs for my case in a day or two.
