I don't know what you need for the first question. When I am physically at 
the machine I can do test reboots. If you have something specific you want 
me to try I should be able to.

Every time I boot with the problem commit, the boot never completes. However 
it does seem to get pretty far. I get multiple register dumps every time. 
After a while (a few minutes) I reboot to a wrking kernel.

The output I included is from: journalctl -k -b -1
If you think it would be better to see more than dmesg output let me know.
