    Subject2.5.67: Stack dumps in ide-scsi code
    Linux-2.5.67
    Asus A7S-VM motherboard with suspected problems (onboard USB, Ethernet
    flaky)
    HP 200j CD/DVD writer
    Duron 950 processor

    While trying to burn a DVD-RW on my HP 200j, a got a rapid series of
    stack dumps. I think the initial dump was different, but scrolled
    out of the buffer.

    Two dumps below repeated (alternating) several times, until hdc (the
    DVD writer) was offlined.

    If the questionable motherboard makes this uninteresting, that's OK.
    I'll have a new MB soon, and re-submit if it still happens.
