The current implementation from Vladimir simply dumps 1 MB of memory contents starting at the base address of the second PCI device (which most likely is the VGA controller on Intel systems). This locks up a number of different systems, e.g. my Ibex Peak-based T410s. This patch documents the issue and stops dumping the graphics registers for the -a/--all parameter.
