hi
  I am working on powerpc(Mpc860T) = with=20 linux-2.4 kernnel,

As I am developping  application using spi and with irqs: =
For=20 each 10 millisec I am getting siu interrupt(timer),In the
interrupt = handler=20 I have to read my device (using spi communication)
I am able to = write it=20 (I am able drive my device)
  All other interrupts I am using = are =20 cpm interrupts(smc2.timer2,spi),one
siu interrupt for the present = ,
 
I am facing the following problems:
1.No more spi read takes=20 place : case-if i tried to do continous serial print using=20 ttyS1(SMC2)
2. if I limited number of times of print then SPI read = will not=20 have probelm
  
How can i solve this with prbklem
 
 thanks to all=20 ...
