    SubjectMemory Access Problem
    Date
    I have a problem in kernel 2.4.4

    I use readw to access memory below 1MB , report "Segmentation fault"
    and stall in memory

    simple code below (this will get paraller port)
    ==
    int init_module(void){
    unsigned int *BIOS_Data=(unsigned int *)0x400;
    u32 test;
    test = readw(BIOS_Data);

    printk(KERN_CRIT "0x400:%x\n",test);
    }
    ==
    but those can work in kernel 2.2.19 , no problem .

    can anyone help me ?
