So you're saying it doesn't output any statistics upon receiving
SIGUSR1, right?

Well, granted I'm running coreutils 8.13-3.2 (and not 8.13-3.1 as you
do, but I don't see any relevant differences in the changelog), this
works just as advertised for me:

  $ dd if=/dev/zero of=/dev/null& pid=$!
  $ kill -USR1 $pid
  7566780+0 records in
  7566779+0 records out
  3874190848 bytes (3.9 GB) copied, 3.28482 s, 1.2 GB/s

So there's probably something else wrong with your system. Are you sure
you're using dd from Debian's coreutils? debsum errors in your bug
report suggest you may not have a clean install.

Hi,

I experience the same issue on a quite newly installed system.
does not output anything. Only at the end of the dd run I get the 'normal' summary.

I experienced this on another of my systems as well in the past, I will verify the
issue on the other systems in the next days.

regards (and happy new year) m
