Default trap handler vector 14

Hello
	Im having a serious problem indicated by this message : 
Default Trap handler: vector 14 : Suspend RT task C305C420 . I know this
is because of a page fault. But i fail to see where this is occuring. I
have 2 modules. One of which is a driver using comedi which only does a
comedi_data_read when asked to do so by the other module. The other
module is a rtai periodic process which used a UP scheduler and also
FIFOs. Both these modules work perfectly independently. And i only get
the error when my real time module calls the driver. And this only
happens some times. Any hints about what could be going on.? Is there an
issue with using RTAI UP scheduler and fifos and comedi?. The trap seems
to be occuring at the point i call the comedi_data_read function or a
comedi_do_insn function. When my driver runs independently it works fine
with no faults.

Thanks

Muks
