From there it was easy. Ok, well, that's -a- possibility... we'll see. I'm doing some more tests to try to characterize the problem a bit better, then we can play with the driver. I think it's also worth trying with earlier kernels in case it's some kind of regression, though that means I'll have to backport my board support for that little box :-) Cheers, Ben. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
