schedule() and mipsel processor

[fpga dsp <fpga_dsp@yahoo.com.au>]

Hi all,

 

I may ask a stupid question here but I have problem of calling any functions such as interruptible_sleep_on_timeout, sleep_on ... in a timer handler, the kernel just crash straight away in the function schedule(). Now I go and do a diff between kern/sched.c on i686 source and mipsel source. clearly , they are different. So the question is from kernel programming point of view, the bottom-half of interrupt handler is still considered interrupt handler? I don't see any platform dependent code in the scheduler at all. So why a mips scheduler is different from intel scheduler ?

 

Many thanks
