Hi, I wrote a kernel module that intercepts open system, it works fine on the console, but when I do an insmod on X, and type anything like "ls", it gives me a segmentation fault. Then I cannot even rmmod the module and I have to reboot. Do you know what causes this? Thanks in advance, Femitha Majeed. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp -- Kernelnewbies: Help each other learn about the Linux kernel.
