Hi all, I'm trying to use printk inside the i386's system_call handler. I just added a printk if the system call is exit... this is the code: msg: .asciz "exit system call\n" ENTRY(system_call) cmp $1, %eax jne go_ahead pusha pushl msg call printk popl %eax popa go_ahead: #original of system_call code comes here I get some nasty OOPS when an application calls int 0x80 with eax=$1 (i.e. calls the exit system call). the message is BUG: unable to handle kernel paging request at virtual address 6c6c696b... anyone has a clue ? thanks a lot, Clay. (btw, this is just me experimenting for educational purposes, it's not something i would ever use in real code, so i'm just trying to understand the bug, i know this is a big no-no code...:) -- Kernelnewbies: Help each other learn about the Linux kernel.
