The machine is running a custom kernel, but nothing very unusual. My instinct is that it may be related to something with the 3c905B 3COM cards that I reported earlier, I'm trying with Intel EtherExpresses right now and getting no fault problems. The double-fault does not occur consistently, unfortunately, and typically only occurs during my rc.local stuff (loading a bunch (100+) of chrooted daemons) on boot-up. Would the eip/esp/ebp values be worth sending? -Troy Cobb Circle Net, Inc. http://www.circle.net > -----Original Message----- > From: Mike Smith [mailto:mike@smith.net.au] > Sent: Monday, February 08, 1999 6:55 PM > To: tcobb@staff.circle.net > Cc: current@FreeBSD.ORG > Subject: Re: Tracking a Fatal Double Fault > > > > Can someone please give me a short guide > > on how to track down a fatal double fault? > > System is 3.0-19990205-STABLE, and I've written > > down the fault info. > > Ack.
