I don't have this card any more. And regarging my SD... I can't do exact measures.

What I have done yesterday is:

; Running at full frequency:

35 iterations!

Oct 16 11:55:46 kibab-nb kernel: mmc_send_app_ocond(): cmd completed in 185 iter 

185 iterations at lowest frequency...

Sorry for long answer delay.
