I'm not a complete newbie, but I thought that this might be the right place for this question.
I was looking at recent messages in a log file (/var/log/warn), trying to solve another problem, and noticed the following entries:
Dec 8 22:52:47 linux kernel: Intel536: no version for "struct_module" found: kernel tainted.
Dec 8 22:52:47 linux kernel: Intel536: no version magic, tainting kernel.
Dec 8 22:52:47 linux kernel: Intel536: module license 'Proprietary' taints kernel.
The module in question is the driver for my Win (or Lin) modem, which works OK (actually seems faster than under windows!) My system appears stable. Do I need to worry about these messages (which seem to occur for each log-in)?
I've tried googling on this, but couldn't find any pages that actually explained the meaning.
