I logged onto my computer as a root and I had root privilages. Yet when I tried to enter the directory fd - the one which contains entry.s - it gave me an error message that I can not enter this directory and it gives me an error similar to the one below:- Do not have permission to open this directory. I am trying to make a system call and I can not do that. Any suggestions? regards, r2 -- Kernelnewbies: Help each other learn about the Linux kernel.
