The bottom line is, you're running a Wifi module and another module that you've complied yourself, your running the nVidia driver. Your kernel *is* tainted. You will/may get messages to that effect. Why they come at times and why they don't at others is immaterial. I've said it before, and I'll say it again. I'm not interested in chasing that....and I won't Unless you're system is failing. Unless your wifi is broken. Unless your graphics are freezing. Your system is running just fine. So, I'm pretty much at an end when it comes to this thread. There are *no* problems to be solved. So, your choice if you want to continue to worry about those messages and if/when they appear or don't appear. So, I'm done. -- A motto of mine is: When in doubt, try it out
