Hi All,
I am working on 79s334A board with 32MB RAM and Linux 2.4.13 kernel.
I have module to be inserted into kernel. The size of the module will be
around 1 MB.
I am using two file systems while building kernel image, one is NFS and
the other is RAMDISK.
When i work with NFS i do not have any problem.
But when i build RAMDISK image and insert the module, insmod is
doing fine. But after that i could not invoke any other application ( even
ps -ef is also giving segmentation fault.)
The RAMDISK size choosen is 10MB and the memory on board is 32MB.
When i did cat /proc/meminfo i found strange thing. All the figures are
corrupted.
The statistics before and after insmod are as follows:
# cat /proc/meminfo
