No, I don't think that is the problem. Where do you see the error

message?

almost at the very beginning of bootup, right after the initialization of the PCMCIA slot.

One possible explanation is that this is a timing problem: the IPv6

initialization of 'lo0' is occurring before the system has set up the

mbuf pool. I have seen this before, in early versions of Darwin, but I

thought that had been fixed.

What kind of machine are you using, and when did this start happening?

It's a Ti Book 667, this started happening round about the time I upgraded to 10.2.4. I think your explanation might explain why when I force shutdown things are back to normal. thanks, Vasisht --------------------------------------------------------------------- Life is complex: it has real and imaginary components _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
