Please consider replacing with the following:

Description: Use ssleep() instead of nicedelay()
to guarantee the task delays as expected. Remove the prototype and
definition of nicedelay(). This is a very weird function, because it is
called to sleep in terms of usecs, but always sleeps for 1 second,
completely ignoring the parameter. I have gone ahead and followed suit,
just sleeping for a second in all cases, but maybe someone with the
hardware could tell me if perhaps the paramter *should* matter. Additionally,
nicedelay() is called in TASK_INTERRUPTIBLE state, but doesn't deal with signals
in case these longer delays do not complete, so I believe ssleep() is more
appropriate.
