    Subject[PATCH 03/77] Staging: hv: storvsc: Increase the timeout value in the storvsc driver
    Date
    On some loaded windows hosts, we have discovered that the host may not
    respond to guest requests within the specified time (one second)
    as evidenced by the guest timing out. Fix this problem by increasing
    the timeout to 5 seconds.

    It may be useful to apply this patch to the 3.0 kernel as well.
    the 3.0 kernel as well.
