    I've got a problem with FreeBSD 4.9-RELEASE resetting
    itself. This is a production system that has been
    running fine for over a year.

    It seems to be linked to a disk error of some sort. I
    often see log file entries like this:

    Sep 23 00:00:46 nfs2 /kernel: ad0: timeout sending
    command=c8 s=80 e=00
    Sep 23 00:00:46 nfs2 /kernel: ad0: error executing
    command - resetting
    Sep 23 00:00:46 nfs2 /kernel: ata0: resetting devices
    .. ad0: DMA limited to UDMA33, non-ATA66 cable or
    device
    Sep 23 00:00:46 nfs2 /kernel: don

    Sep 29 11:49:01 nfs2 /kernel: ad0: READ command
    timeout tag=0 serv=0 - resetting
    Sep 29 11:49:01 nfs2 /kernel: ata0: resetting devices
    .. ad0: DMA limited to UDMA33, non-ATA66 cable or
    device
    Sep 29 11:49:01 nfs2 /kernel: done

    Oct 9 21:40:55 nfs2 /kernel: ad0: READ command
    timeout tag=0 serv=0 - resetting
    Oct 9 21:40:55 nfs2 /kernel: ata0: resetting devices
    .. ad0: DMA limited to UDMA33, non-ATA66 cable or
    device

    All I can figure is that the FreeBSD system is trying
    to read/write to ad0 (my primary HD) and there's an
    error of some sort, so it waits a bit and then resets
    the entire system.

    When I do an fsck, it comes out fine. So it's
    definately some sort of weird intermittent problem.

    Is my HD toast, or is FreeBSD acting stupid
    unnecessarily?
