Hi Jeff,

Thanks very much for your help. I have enabled the interrupts for
SystemACE now. And in fact xsa_complete_request() was never called. I
fixed that in xsa_thread.

I was wondering if you could send in your modifications to the
xilinx_systemace/* files so that I can know better where else the
potential problems may lie.

Do I need to have a device entry for xsystemacea (0/1) in my /dev
directory ? If yes, then what should it be like ?
