Well, I was using some old kernel there and updated to the 2.6.38 recently so only clue I do have is that it was working on like 2 years old kernel. And bisection is quite complicated, as number of kernel images simply doesn't boot there. :( I will look on this next week (hopefully) thanks anyway for your help so far. -- metan -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
