Hi all,

Any clues as to why a callback function would only work if I use the
COMEDI_CB_EOA flag and cause a system crash if I use the COMEDI_CB_EOS
flag?

I'm building and executing the comedi_cmd from the init_module routine.
And, like I said the callback works fine as long as it is only
registered with the COMEDI_CB_EOA flag.  Also, it doesn't matter if the
body of the callback is commented out or not.  It will always crash if I
use the EOS flag but work if I use the EOA flag.  The command it self
only reads one channel 10 times with a 1 second interval between each
read.

How do I trace the problem down?

Thanks,
Evan
