Mmh, the critical path is between modprobe and ifup? Does it also apply on the rt-driver? Anyway, can we say this is basically a vanilla problem? The usual reply of the kernel folks on such reports is: "Have you already tried latest shiny git?". This would likely be http://www.kernel.org/git/?p=linux/kernel/git/jgarzik/netdev-2.6.git;a=tree;h=51578697d4994715151e6484f27793c2d5ee7262;hb=95064a75ebf8744e1ff595e8cd7ff9b6c851523e;f=drivers/net/e1000 (netdev-git) We may also move the generic part of this thread to LKML or netdev if we can exclude that this issue was already fixed elsewhere. There we may at least gain some numbers on that magic startup delay... Jan
