The following panic is from the /kernel.GENERIC as shipped with 3.4-RELEASE; it's copied here via a piece of paper, so apologies for the bogus formatting: Fatal trap 12: page fault while in kernel mode fault virtual address = 0xd45d6f54 fault code = supervisor read, page not present instruction pointer = 0x8: 0xc015d301 stack pointer = 0x10: 0xc45d6e04 frame pointer = 0x10: 0xc45d6f60 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 = 14552 (sh) interrupt mask = trap number = 12 panic: page fault The machine passes all the anal memory checks the bios can throw at it. There are no ISA peripherals in the machine, and no other devices that the kernel seems to fail to recognise. I can enumerate the hardware if it's relevant... Just wondering whether this rings bells for anyone? What's up with this? Other symptom: ldconfig would routinely segfault and dump core following a bare install of 3.4-RELEASE. I cvsuped the full source in order to build stable, and a stable ldconfig build doesn't exhibit the same problem. dmesg follows. Copyright (c) 1992-1999 FreeBSD Inc.
