I used FreeSBie to disable each of these services in rc.conf and was able to successfully boot and log in. Though if I attempt to run ssh, sshd, fetch, etc the same page fault occurs, though I can succesfully run ping, traceroute, and dhclient. I tried a different ethernet card with no effect. I followed the handbook instructions and make a kernel dump and savecore and attempted to debug the kernel with kgdb. The information I got from these operations is below: Unread portion of the kernel message buffer: kernel trap 12 with interrupts disabled Fatal trap 12: page fault while in kernel mode fault virtual address = 0x74 fault code = supervisor read, page not present instruction pointer = 0x20:0xc06983fd stack pointer = 0x28:0xe9279be0 frame pointer = 0x28:0xe9279be4 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 3153 (sshd) trap number = 12 panic: page fault Uptime: 21h51m42s Dumping 1023 MB (2 chunks) chunk 0: 1MB (160 pages) ... ok chunk 1: 1023MB (261886 pages) 1008 992 976 960 944 928 912 896 8 80 864 848 832 816 800 784 768 752 736 720 704 688 672 656 640 624 608 592 576 560 544 528 512 496 480 464 448 432 416 400 384 368 352 336 320 304 288 272 256 240 224 208 192 176 160 144 128 112 96 80 64 48 32 16 #0 doadump () at pcpu.h:165 165 pcpu.h: No such file or directory. in pcpu.h I have some C programming experience and went to line 165 in pcpu.h but I was unsure what to do, the line was an assembly call and looked important. I did not have this issue upon initial install so I'll probably just reinstall and go with the cd builds or try 6.2 RC2. I would be happy to provide the dump or more information upon request. >How-To-Repeat: Run most network applications on my particular setup and hardware. >Fix: I am a single user and this is not very important, I was just curious about what was going on, do not invest effort if this looks to be a fruitless effort. >Release-Note: >Audit-Trail: >Unformatted:
