hf mf mifare not working

Dear forum members can anyone help out this, how to fix this problem? Seems I get incorrect ks par nt and get this error

Key not found (lfsr_common_prefix list is null). Nt=XXXXXX

and it's impossible to recover key I had tried more than 10 cards with same results, with previous revision (few months ago) I recovered keys with hf mf mifare without any problems on same cards, so there is bug? I can't find it please help me

Re: hf mf mifare not working

What does the reported par-value look like in those examples?
What does hw version give?

Perhaps this is the same issue as the (now solved but still unpatched) http://www.proxmark.org/forum/viewtopic.php?id=1556
