Dear Aroop, Well that depends on the kernel as I guess. I am using 2.6.10 kernel (Intel based system). I heard that this problem of 'Bad Address' is NOT present on 2.4.x kernels. What kernel are you using?
I just have doubt here. Does the /dev/mem device represent the entire physical memory on the system? Please through some light on this. How do I interpret the /proc/meminfo and iomem interfaces?
