Could we see the code somewhere? it's hard to judge just by reading the "raw facts" you wrote here. But IMO, as long you just deal with the time slice calculation algorithm, it shouldn't introduce trouble...but once you touch other things like for example you put tasks into multi queue, changing the way a task is kicked out of the running queue etc, it might be the cause. NB: you need full system emulator I guess, like Qemu...put your kernel there...build it as debuggable kernel..and hook gdb into Qemu's gdb stub. It is not 100% identical to real machine behaviour...but at least you don't need to kick your reset button everytime it hangs... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
