There's a patch that you have to apply to the kernel for this. It came
up on Linux-Kernel a month or two ago, however Linus refused to apply it
to the source treee claiming that it only allowed people to continue

all correctly). Take a look at the l-k mailing list archives at somewhere
like www.tux.org and try searching on this.
