I am having a major problem with a FreeBSD-4.3 machine. I dredged through the mailing list archives, and did not find any useful answers. I am hopeful that someone here can help. The machine is currently running 4.3-RELEASE from a CD install. After installing it, I shipped it away to a datacenter which is its intended long-term home. When the machine came up, I logged in and immediately began a cvsup in preparation for bringing the machine up to the head of STABLE. Within a minute or two, the machine was totally unreachable and unresponsive on the network. A reboot brings the machine back online, but it falls off the net again reliably within about 10 minutes. It stays up a bit longer if the network is not being used heavily. The motherboard is an Intel 815SET Easton with onboard NIC. The relevant kernel messages at boot time are: Jul 31 17:08:17 phl /kernel: FreeBSD 4.3-RELEASE #0: Sat Apr 21 10:54:49 GMT 2001 Jul 31 17:08:17 phl /kernel: jkh@narf.osd.bsdi.com:/usr/src/sys/compile/GENERIC Jul 31 17:08:17 phl /kernel: Timecounter "i8254" frequency 1193182 Hz Jul 31 17:08:17 phl /kernel: CPU: Pentium III/Pentium III Xeon/Celeron (797.42-MHz 686-class CPU) Jul 31 17:08:17 phl /kernel: Origin = "GenuineIntel" Id = 0x68a Stepping = 10 Jul 31 17:08:17 phl /kernel: Features=0x383f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE> ... Jul 31 17:08:18 phl /kernel: fxp0: <Intel PLC 10/100 Ethernet> port 0xdf00-0xdf3f mem 0xff8ff000-0xff8fffff irq 11 at device 8.0 on pci1 Jul 31 17:08:18 phl /kernel: fxp0: Ethernet address 00:03:47:a0:49:91 Whenever the machine is falling off-net, the only thing logged looks like this: Aug 9 16:27:02 phl /kernel: fxp0: SCB timeout Aug 9 16:27:02 phl last message repeated 17 times Aug 9 16:27:02 phl /kernel: fxp0: device timeout And then the machine remains off the net until rebooted. Is there any known fix for this? All of the messages that I see on the mailing list archives that have "solutions" involve switching out the hardware for a different NIC. As that would involve having the machine shipped back home and then out again, this is very undesirable. I can usually keep the machine on the net for at least a few minutes at a time before it hangs, so if anyone has any idea how I could possibly fix this remotely I would be greatly appreciative. If there is no way to fix this remotely, that knowledge would also be useful as I will then move ahead with the RMA of the machine. In any case, thank you all in advance for any assistance.
