The latest panic is with the 3.3-RC source as of about Sept 11 22:00 PDT. This box in question is doing NFS for 2 workstations (only one is really being used), and running named, squid and ppp -nat for my home LAN. It seems to panic about half way through a make buildworld every time. I would be more than happy to provide more information as necessary. I'm by no means a kernel hacker so I'm not really sure exactly what info is needed. I'm trying to reproduce this panic yet again with a kernel compiled with debugging symbols so I can run it through kgdb. For now this is all I have, but more info may follow. Below is the dump and my dmesg: Fatal trap 12: page fault while in kernel mode fault virtual address = 0xffff037f fault code = supervisor read, page not present instruction pointer = 0x8:0xffff037f stack pointer = 0x10:0xc4651c58 frame pointer = 0x10:0xc4651d1c code segment = base 0x0, limit 0xffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interupt enable, resume, IOPL = 0 current process = 78631 (cc1) interrupt mask = kernel: type 12 trap, code=0 Stoped at -0xfc81: Fatal trap 12: page fault while in kernel mode fault virtual address = 0xfff037f fault code = supervisor read, page not present instruction pointer = 0x0:0xc020327c stack pointer = 0x10:0xc4651ad0 frame pointer = 0x10:0xc4651ad0 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 = 78631 (cc1) interrupt mask = kernel: type 12 trap, code=0 Copyright (c) 1992-1999 FreeBSD Inc.
