My first attempt to do the copy resulted in a crash but I have a USB keyboard so I could not get a stack crawl. I reformatted the partition and tried again taking care to intentionally enter KDL once so the keyboard would be enabled if I ended up in KDL again. Contrary to what I expected, the copy concluded without problems. I opened a terminal window and ran sync just in case. Then I tried to unmount the destination partition (the one I copied the data to) and got into KDL with a crash in the block cache. GCC2 r32639.
