    SubjectRe: Beaver In Detox AND IEEE1394 badness message
    From
    Date
    Re this problem: I just installed Arjan's test11 kernel and I can still
    see only 1 of 3 firewire devices on my system (gscanbus sees all 3 and I
    see from log messages that at least part of the code sees more than 1).
    But /proc/scsi/scsi only has:
    cat /proc/scsi/scsi
    Attached devices:
    Host: scsi0 Channel: 00 Id: 00 Lun: 00
    Vendor: Maxtor Model: 5000XT Rev: 0100
    Type: Direct-Access ANSI SCSI revision: 06

    I also see these slab errors. Relevant parts of dmesg output are:
