Well, I tried the procedure mentioned in comment#4 of http://wwww.ubuntuforums.org/showthread.php?t=1471399, by booting my system into rescue mode. But this did not help me either, still same behaviour! Paulo could be right, the main culprit seems to be at this point: "Calling ibm,client-architecture-support...\" Usually I have seen output of above command either as "done" or "not implemented", but in this case it is just ...(nil). Is open firmware failing to validate for "client-architecture-support" here? OR something missing in pHyp support? ------- Comment From iranna.an...@in.ibm.com 2014-06-27 11:46 EDT------- (In reply to comment #6) > Also, do you mind installing with Ubuntu 14.10 alpha images? > > http://cdimage.ubuntu.com/ubuntu-server/daily/current/utopic-server-ppc64el. > iso Sure, I will give this try on Monday.
