hi
I am working on powerpc(Mpc860T) with linux-2.4 kernnel,
As I am developping application using spi and with irqs:
For each one millisec I am getting siu interrupt,In the
interrupt handler I have to load frequency(using spi communication)
I am able to write it (I am able load the frequency also)
As I am developping application using spi and with irqs:

All other interrupts I am using are cpm interrupts(smc2.timer2,spi),one
siu interrupt for the present ,
I am facing the following problems:
1.system rebooting: case-if i tried to write continuously to externel hardware through spi ,in externel (siu)intrrupt handler,and timer2(cpm)intrrupt handler,
2. if I limited number of times of write to hardware system not getting rebooted.

2. if I limited number of times of write to hardware system not getting rebooted.
I observed that the problem occured due to passing of control signals to externel hardware (those are memory mapped signals) in irqs.how can i solve this with getting rebooted.
thanks to all ...
