I've been having trouble with my server after I installed 4.0-Stable. It seems that the server will reboot automatically whenever network traffic is idle. The following message was received on the console as I tended to my most favourite little household plant. It's small (about 4 inches tall), and it's got little reddish-purple buds. ~~~ Fatal trap 12: page fault while in kernel mode fault virtual address: 0x8 fault code = supervisor read, page not present instruction pointer = 0x8:0xc01cd748 stack pointer = 0x19:0xc02f7804 frame pointer = 0x10:0xc02f780c code segment = base 0x0, limit 0xfffff, type 0x1b, DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = Idle interrupt mask = trap number = 12 panic: page fault syncing disks... 19 11 done (The kernel is still GENERIC, so if anyone knows about these things perhaps you can point me to the function that the instruction pointer is addressing. I would do it myself if I could translate the produced data.) ~~~ I haven't modified anything at all since my upgrade from 3.4-Stable (3.4 gave me no trouble whatsoever). Although, since I discovered this problem, I have replaced absolutely *every* piece of hardware in the server except the network cards. I've go two Realtek 8139 NICs (rl0 & rl1) installed at the moment, but I've got nothing to replace them with. I'm pretty sure that the NIcs are the problem as the server's uptime was at 5hrs when the NICs weren't in use. Once an internet connection was plugged into one of them, however, the server was down in less than 15 minutes. =( (The morning after the install, after I had finished watering my plant, I had discovered that the server had rebooted itself aprroximately 20 times.) Does anyone know if there is a bug with the Realtek drivers? If so, how do I fix this problem? If anyone has any other suggestions as to what the problem might be (even if it's not the NICs), I'm open to ideas. I've been working on this for 6 days now to no avail - I used to think I knew what I was doing. Oh well, at least I still have my plant - that little guy has grown two buds since this problem started! Anyway, thank-you in advance for your assistance! -David P.S. I can produce copies of any config files that might help upon request. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
