Please consider replacing with the following patch:

Description: Use msleep()/ssleep() instead of schedule_timeout() to guarantee
the task delays as expected. TASK_INTERRUPTIBLE is used in the original code,
however there is no check on the return values / for signals, thus I believe
TASK_UNINTERRUPTIBLE (and hence msleep()) is more appropriate.
