The following reply was made to PR i386/151896; it has been noted by GNATS. From: Remko Lodder <remko@elvandar.org> To: Karl-Heinz Wild <kh.wild@barga.com> Cc: freebsd-gnats-submit@FreeBSD.org Subject: Re: i386/151896: increasing kmem_size in loader.conf panic Date: Tue, 2 Nov 2010 21:11:26 +0100 Hello, Yes.. I cannot make it better :-), if you have access to the machine and = it isn't production or can have some downtime, you should backup the data on it, and reinstall the system or to be quicker overwrite the base = system with amd64 binaries, you should however rebuild your ports and re-import the data you backupped (exported). Especially with = databases and stuff, because 'replacing' that wont work.
