That got rid of the esp0: !TC on MSG OUT messages, but "ls" still
doesn't work, and "dd if=/dev/rsd0c" says 0 bytes transferred, etc...
I don't get how I can still run programs and read/write files, but not
be able to read the raw disk device. And something interesting: if I
boot single-user, mount -u /, and ls, nothing shows up. But if I then
ls>somefile (or otherwise create a file), ls works perfectly (for that
directory only... if I ls another directory, it still looks empty).

All of it? It printed a _lot_ of stuff :) Here's the output from a "dd
if=/dev/rsd0c" (after running dd once first, so that dd itself will be
cached in RAM):

# dd if=/dev/rsd0c
