hai all,
     Is it possible to call call_usermodehelper from interrupt context.
I want to call a user program from the keyboard driver. When am calling, 
it is hanging, and giving the error that
    <0> Kernel panic : Aiee, killing interrupt handler
        In interrupt handler -- not syncing.
I am using Redhat linux 9.

Can anybody please help me.


  Thanks&Regards,

   P.Manohar,

No.  You'll need to run schedule_work() and then run call_usermodehelper()
from within the work function.

Of course not! I've seen this message before. Either it's a joke
or you have no clue about what interrupts are.
