kernel thread does not wakeup

[Veda N]

Hi,
   I am having a driver during initialisation i create a thread using
kthread_run.
   As soon as the initialisation function is complete. I start getting
interrupts.

   The kernel thread waits on a struct completion using
wait_for_completion_interruptib
le  function.
   Whenever an interrupt arrives i call the function complete to
wakeup the thread.
   For somereason the kernel thread does not awake.
   I have put some debug prints to see if the address struct
completion is the same.
   It gives the address to be same.

   I dont know why the kernel thread does not wakeup.

   Is there any restriction of using kernel threads during the linux
kernel bootup?.

  What i am trying to say is can i make a thread go sleep during linux
kernel bootup
  and wake it up during kernel bootup upon occurance of an interrupt.

Regards,
vedan
