Comment 6 for bug 94821

I guess this is probably the culprit.

ubuntu@ubuntu:~$ ps wallx | (IFS=''; read h; echo "$h"; fgrep -w dd)
F UID PID PPID PRI NI VSZ RSS WCHAN STAT TTY TIME COMMAND
4 0 11485 1 15 0 1836 536 syslog S ? 0:00 /bin/dd bs 1 if /proc/kmsg of /var/run/klogd/kmsg

fox123: do you get the same result? If you find other instances, a pstree(1) printout might be helpful, too.

FWIW I'm not seeing anything like this, also I'm curious as to how you connected dd(1) to these errors in the first place.
