The complete kernel panic is what is needed to get anywhere with this.

If all else fails, get a digital camera and take a picture of it,
although you may need to reconfigure your console to get enough lines
displayed. A console down a serial line to another computer is the best
way of capturing these though.

Just on a hunch, check if you have 4K stacks turned on, if you do, go
back to 8K stacks and see if that cures it.
