Hello, I tried the kernel module programming tutorial (exactly same code) found on the following link:
http://tldp.org/LDP/lkmpg/2.6/html/x121.html The module was successfully compiled, then used insmod to insert into the kernel. It was properly listed in /proc/modules. # cat /proc/modules | less hello_1 9600 0 [permanent], Live 0xffffffffa0440000 (P) But when I tried removing the module, # rmmod -f hello-1 ERROR: Removing 'hello_1': Device or resource busy How should I fix this? Other useful info: # uname -a Linux mypc 2.6.27-7-generic #1 SMP Fri Oct 24 06:40:41 UTC 2008 x86_64 GNU/Linux # cat /proc/version Linux version 2.6.27-7-generic (bui...@yellow) (gcc version 4.3.2 (Ubuntu 4.3.2-1ubuntu10) ) #1 SMP Fri Oct 24 06:40:41 UTC 2008 Thanks! -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecar...@nl.linux.org Please read the FAQ at http://kernelnewbies.org/FAQ
