In sato-sdk image, the dd command is from coreutils package:
#########
root@p1022ds:~# which dd
/bin/dd
root@p1022ds:~# 
root@p1022ds:~# ls -l /bin/dd*
-rwxr-xr-x 1 root root 88300 Jul 19 11:39 /bin/dd.coreutils
lrwxrwxrwx 1 root root    17 Jul 24 19:32 /bin/dd -> /bin/dd.coreutils
root@p1022ds:~# 
##########

Run a test for dd, still segfault:
#########
root@p1022ds:~# dd if=/dev/zero of=testfile count=1
1+0 records in
1+0 records out
512 bytes (512 B) copiedSegmentation fault
##########

In sato image, the dd command is from busybox package:
##########
root@p1022ds:~# ls -l /bin/dd*
lrwxrwxrwx 1 root root    19 Jul 30 06:19 /bin/dd -> /bin/busybox.nosuid
#########

This dd command works well:
###########
root@p1022ds:~# dd if=/dev/zero of=testfile count=1
1+0 records in
1+0 records out
root@p1022ds:~#

This issue happens on nfs and sata disk.

Can you verify this on non ppc hardware and in qemuppc, I would like to know if 
it occurs elsewhere or limited to the p1022ds platform.

Also, please verify if thes was a problem with an eariler milestone build and 
let me know which GIT Hash you are building.  This could be 
a compiler issue, or maybe eglibc related.  If you can test with the older 2.17 
eglibc that might be helpful.

Thanks

Run dd command in p1022ds hardware , still segfault:
#########
root@p1022ds:~# dd if=/dev/zero of=testfile count=1
1+0 records in
1+0 records out
512 bytes (512 B) copiedSegmentation fault.
##########

I test with the older 2.17 eglibc and there is still the issue in p1022ds
