Task Queues

Hi All,

I am trying to create an ISR for our hardware that implements a
"bottom half" interrupt handler. I use a task queue to do this
since our driver is a loadable module. Everything works fine
except that if the task is added to the tq_immediate task queue
it does not seem to run. If I use the tq_scheduler task queue
it works fine. I gather that for bottom halfves that it is
appropriate to schedule them on the immediate queue.

I have also tried running other tasks that are scheduled elsewhere
in the driver, and have the same problem.
