    Hello,

    I have one FreeBSD server, that recently started to behave strangely.
    It has been rock-solid for all of its existence (almost 2 years).
    Recently I upgraded it to RELENG_4_9 and it started crashing with
    kernel panic approximately every 24 hours, but this varies.
    I have tried downgrading to RELENG_4_8 and RELENG_4_7 - the same
    thing keeps happening. I have also moved the harddrives in a brand
    new, albeit identical machine - Duron 800 MHz, 512MB RAM,
    Adaptec 29160 Ultra 160 SCSI, two Fujitsu disks in Vinum RAID1.

    Here is the kernel panic:

    Fatal trap 12: page fault while in kernel mode
    fault virtual address = 0x485974e2
    fault code = supervisor read, page not present
    instruction pointer = 0x8:0xc01cbfe3
    stack pointer = 0x10:0xc0311854
    frame pointer = 0x10:0xc0311858
    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 = Idle
    interrupt mask =
    trap number = 12
    panic: page fault

    attached are the kernel configuration and the dmesg.
    Please, can anyone shed any light on this? I thought it was the hardware,
    but I've changed everything except the hard disks - new case, new powersupply,
    new motherboard, new processor, new RAM, new Adaptec.

    Thanks in advance.

    -tacho
