My problems partially went away with the Dave Arlie's "drm-next" kernel. I've had one crash when I attached the second monitor to the dock. I was unable to record any output from the kernel. I rebooted and everything works fine. So far so good.
output from uname -r: 4.6.0-996-generic
downloaded from: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/2016-04-15-wily/
Mainline does not work. I get a "soft lockup" warning from the NMI Watchdog and the boot goes nowhere.
