Amith, Thanks for this information. I did attempt to use sys_open earlier and it failed as unresolved symbol when did an insmod on the object file. Is there a library that I need to link with my module before insmoding it that contains the definition 'sys_open'? thanks, Brad The information contained in this message is confidential and is intended for the addressee only.
