    I haven't been able to run a vinum volume for a few
    weeks and with the latest geom_vinum checkin, I was
    hoping that would fix my problems. but I get
    something else with that (it refuses to start p1 so
    that it can start rebuilding and I get a crash on
    mount...but thats a different email :)).

    I type the following commands once the system comes
    up:

    vinum
    (while @ the prompt)start

    and it crashes.

    I'm got the following from the crash:

    Fatal trap 12: page fault while in kernel mode
    cpuid = 0; apic id = 00
    fault virtual address = 0x88
    fault code = supervisor read, page not
    present
    instruction pointer = 0x8:0xc05bdc50
    stack pointer = 0x10:0xd11659b4
    frame pointer = 0x10:0xd11659cc
    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 = 573 (vinum)
    kernel: type 12 trap, code=0
    panic: from debugger
    cpuid = 0;

    Fatal trap 3: breakpoint instruction fault while in
    kernel mode
    cpuid = 0; apic id = 00
    instruction pointer = 0x8:0xc075360e
    stack pointer = 0x10:0xd1165798

    type 0x1b

(kgdb)
for the record, when geom_vinum brings up and reads
the volumes (there are 2 plex's) it comes up and has
the following:
mp3.p0 is up
mp3.p1 is down
Let me know if there is anything else I can do to help
you debug this problem.  I will make another post with
my geom_vinum problems :)
