I guess I will have to try to get vmcore to have any chance to interest someone with it. And that won't be easy as the box has 16GB of RAM and, unfortunately, the FC array we used, is normally connected to the production box and we can't really experiment on it freely. [1] dmesg (non-verbose; verbose one is far too verbose, thanks to mpt; and without the mentioned before da1, as we had to reconnect the array to the proper machine) attached. -- Krzysztof Kowalik | () ASCII Ribbon Campaign Computer Center, AGH UST | /\ Support plain text e-mail --rwEMma7ioTxnRzrJ Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="dmesg.boot" Copyright (c) 1992-2005 The FreeBSD Project.
