I did a It does not occur in the kernel. This message is from one of the programs which are started during boot, e.g., in /etc/rc. This program's name is (didn't you guess it from the error message): savecore I had exactly this problem and solved it by looking at three things: 1. If you had a line containing ... root on as0 swap on as0 in your config file (e.g. SCSITEST), you should change that to ... root on sd0 swap on sd0 2. Look at the "swap386bsd.c" file in your configuration directory This should include something like "sd0". 3. Do a "disklabel -r sd0". If it doesn't show something like b: .... swap ... then this could be another cause of your problem. You have to fix it. I won't recommend writing a new disklabel here, because after my bad experience with disklabel I am very careful using it. Do not misunderstand this statement. The actions "disklabel" did to my harddisk were all caused by me ! >strings 386bsd and the only string 'as' was in wdswfdwtas (or something like ) >which I located in autoconf.c.

I guess that your system is using swap space. However the "savecore" program couldn't find the device, that's it. >Any help/comments etc. are much appreciated. Hope it did. I am sorry, I can't be more specific, but I have the system at home and I am at work, now.
