For the record: I don't think it relates to a distribution being "recent" at all -- the noise happens with my board with recent kernels and does not with older ones even though the userland is always the same. Something must have changed within the kernel itself and it may be worth investigating what, why and whether it is legitimate. I fear the change may be papering over some bug elsewhere. Maciej
