Bad ones can cause all sorts of hard-to-explain problems. If you have a spare case with a power supply, how about putting all the other bits in there - you seem to have had lots of practice building machines recently, so it won't take too long... I had a machine recently that would work when all the bits were wired together on a formica tabletop, with the disks balanced on books. When assembled in the case, it said there was a keyboard error, and wouldn't boot - even with a known good keyboard. The fourth time I reassembled it, it worked, and has been stable since. -----Original Message----- From: John Straiton [mailto:jks@clickcom.com] Sent: Thursday, September 14, 2000 9:47 AM To: questions@FreeBSD.ORG Subject: Spontaneous Reboot problem I have a machine at home that is about to drive me nuts. For the last 6 months it's worked fine with one exception. I could not do a buildworld. About midway through the attempts, I would get a kernel panic. Occationally it would seem to do it if I was doing the occational packetsniffing. (then again I only use the machine for a couple of things) If I used the machine for anything more than a nat gateway and a fileserver, this would have bothered me more, but in this case it didn't. *however* About 3 days ago it started getting into the habit of panicing very frequently, doing anything, or seemingly nothing sometimes. Samba operations seem to be the absolute worst for forcing it into this error that causes the reboot. Usually by clicking "Network Neighborhood" on a machine on the local lan (Ethernet through a Cisco Cat2908) would cause about 4 copies of SMBD to fire up and then about 10 seconds later cause this error: "Integer divide while in kernel mode" yadda...yadda... Rebooting in 15 seconds... After which the Windows machine would claim the network was unbrowseable. Now, in my experience, panics in a -STABLE or -RELEASE branch are usually hardware error, so I went to swapping out hardware. I swapped the K6-200 for a Cyrix150+ i had laying around, and swapped the memory (128M Dimm for 4 16M Simms). Still a problem, so I reseated all the cards in the machine. Still broken, I took everything out and put a new motherboard with a k6-2-300 processor into a machine using 2 other 16M Dimms I had and then replaced the video card with an identical spare I had. Still broken, I removed the SoundBlaster ISA card and was now able to browse "Network Neighborhood" without causing a panic and was able to buildworld (which I did). However I *still* get these panics, just less frequently. Now before I swap out the last 3 things left ( 2 NIC's and the Hard drive), I thought I'd get suggestions from the list as to what might be going wrong so I don't have to reinstall this machine.. I'd give a uname but the machine panics when I try to telnet or ssh to it so from memory it's a 4.1-STABLE machine with a barely custom kernel.The mods to GENERIC that I made were to add options IPFILTER options IPFILTER_LOG options QUOTA device pcm and then recompile. The buildworld and kernel build were both done last night from a CVS the day prior. It currently is a K6-2-300 w/ Asus P(3?)B-A MB & 2 16M Dimms. 1 Intel NIC, 1 3Com NIC, Matrox Mystique & Maxtor 30GB HD. No CDRom. It was a K6-200 w/ Asus TX97e & 1 128M Dimm, 1 Inet NIC, 1 3Com NIC, SoundBlaster ISA (maybe a 64Value?) Matrox Mystique & Maxtor 30GB HD. Still no CDROM (removed after install). Any suggestions that would keep me from having to reinstall the machine (and gigs worth of ports cause I like it ready for anything...) would be appreciated.
