Strange. I really wonder what's so different on my boxes. Did you try
it with Debian Unstable kernels? Or rather with Debian Stable kernels?
Maybe there changed something which causes this behaviour. (I haven't

Ok, downgrading that one to wishlist (via Bcc to control@b.d.o) as it
is probably a seldom corner case and hence more a feature request than
a real bug. At least "important" is not the proper severity for that
