that's quite sad but as aboves gives no hint on where we would perform
that badly nor why those freezes that i cant reproduce happen.
i'd have to close the bug. the only big difference i know about our
kernels is that ubuntu uses a pata driver instead of the old ide ones.
could that make the difference?
