However, suddenly, when I boot the system, I get a message:

WARNING: The TPM could not be initialized

I didn't know what TPM was, I didn't care, and I just
booted up.  Not my problem.

Except suddenly I have no network card (!)  bge0 is
just invisible - it is no longer in my system.  As far
as FreeBSD is concerned, it is gone.

So what is going on ?

According to Dell's tech support forums, this TPM module is designed to disable parts of your computer such as the NIC if it doesn't find the right keys or whatever it is supposed to contain. Trying to reinstall the TPM drivers under Windows isn't enough to reset the TPM module to a sane state, reportedly.

In other words, if it screws up, your machine becomes hosed. Welcome to trusted computing.

So the bottom line is:  why did this suddenly show up,
and how do I get rid of it ?  I just need my bge0 back...

Supposedly you need to RMA your laptop. Or, better yet, replace it with something else that doesn't contain defective hardware which locks the owner out of their own machine....
