This is one (of many) cases where I made a decision about replacing set_current_state(TASK_INTERRUPTIBLE); schedule_timeout(some_time); with msleep(jiffies_to_msecs(some_time)); msleep() is not exactly the same as the previous code, but I only did this replacement where I thought long delays were *desired*. If this is not the case here, then just disregard this patch. Thanks, Nish Applys-to: 2.6.7 Description: Uses msleep() instead of schedule_timeout() to guarantee the task delays at least the desired time amount.
