Ok, Did a little more research. This error is probably why it takes longer than anticipated to boot, but is unrelated to the crash of the OS.
The error which causes the kernel panic is due to the ethernet driver - smsc95xx. It is documented here and appears to be fixed in a later kernel.

I'll experiment with the pacman.conf file and see if I can install motion without upgrading the rune packages already installed. I wonder if pacman.conf can be edited in the default rune OS package so that the OS does not get broken if someone does a pacman -Syu. the redis error comes to mind as one that could maybe be resolved by putting redis in the 'do not upgrade' list.
