--- Comment #72 from Martin Andersson g02maran@gmail.com --- I have now run another 12+ hour test without problems, where I disabled both sclk_ss and mclk_ss and disabled the clock limiting code (even though I didn't see any difference to the clock speeds).
So at least for me it seems very stable with both sclk_ss and mclk_ss disabled. I will continue using it to see if I will run into any problems.
