From the responses I am getting it seems that the meaning of 'taints

Here's my understanding of it from when I had nVidia graphics. Let's
say that you have a kerneloops, but haven't rebooted. Your kernel is
considered to be tainted by that because anybody trying to recreate a
later kernel issue can't properly know what state the kernel was in.
If you have any binary modules loaded that are closed source, your
kernel is considered tainted because there's no way to troubleshoot
that module or find out if it's involved. (My personal opinion is that
in this case somebody should try to recreate the issue with an
untainted kernel to see if that module's involved, but I guess that's
too much bother.)
I'm not sure at the moment whether the nvidia module being used is the
binary one or the one I compiled from source, but I also compile my wifi
driver from source and the 6 mouse modules are also compiled from
source, and I am trying to understand why the taint messages, especially
the out-of-tree module message, flip-flop between nvidia and my wifi
driver, but they have never been produced by the mouse drivers, even
though all 3 are compiled through dkms and all the compiled modules are
located in the same directory. The dkms.conf file for the mouse driver
is different from the file for the wifi driver, but the dkms.conf files
for the wifi and nvidia drivers are the same.

Steve
