A while ago (first Plumbers conference?) someone was talking about
using a 2-d barcode to display the tail of the kernel log & oops
register data - with the plan that you could capture the image with
a cell phone camera, and then get all the oops data without worrying
about transcription errors as you wrote down & re-typed all the hex.
Anyone know what happened to that plan?
