md5sum of the iso is correct.

== Comment: #5 - Thierry Fauck <thierry.fauck at fr.ibm.com> -  ==
This is a known bug in grub (vsx) which is supposed to be fixed upstream today (see Paulo's patch). Ubuntu will pick the patch as soon as it will be released.
Would you mind check next monday daily build ?
Thanks

== Comment: #6 - Shawn T. Wright <shawnw at us.ibm.com> - ==
I hit this issue as well today.  Will run with older build until fix provided.

Current daily image got from http://cdimage.ubuntu.com/ubuntu-server/daily/20140929/utopic-server-ppc64el.iso is having same problem.
