    Good Evening All,

    I've tried this on several machines now, all of different specification, manufacturer and am still coming across this same problem...

    Whenever I try to ifconfig cue0 up the machine panics, hand typed panic message below.

    Fatal trap 12: page fault while in kernel mode
    Cpuid = 0; apic id = 00
    Fault virtual address = 0x8
    Fault code = supervisor read, page not present
    Instruction pointer = 0x8:0xc05d3960
    Stack pointer = 0x10:0xca5f18bc
    Frame pointer = 0x10:0xca5f18d4
    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 = 116 (ifconfig)
    Trap number = 12
    Panic: page fault
    Cpuid = 0

    I have filed a PR on this, but I have not had any responses from it
    (http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/75710).

    The panic there is from a compaq armada 110 notebook, but I get the same panic (same 3 pointers) on a toshiba satellite pro a40 and on a self built p4 machine along with several others.

    It affects 5.x 6.0 (all the way up to BETA5) but it works flawlessly with 4.11-STABLE/RELEASE.

    Does anyone have any new fresh ideas about this one?

    This is 100% reproduceable so I can try this at anytime,

    Best Regards,

    Graham Lilley

    P.S - going to try building a custom kernel with debugging, if I am able. Currently no src due to lack of network connectivity.
