I must resolve this problem. What code is causing that failure by asking for memory that you do not have?

As was already stated, the use of "real-time" has nothing to do with those options, or memory allocation, or anything else here. Please do not get confused about the determinisitic operation of interrupts/scheduling vs. anything else. > It's easier to encounter such a problem since the said options are disabled. Then fix your broken driver that is asking for so much memory on a system that does not have it. Do you have a pointer to your driver anywhere so we can review it? good luck! greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
