Running -current from March 11 on a dual cpu compaq 5100, there are some
warnings in the dmesg about the tl ethernet interface.
Here are the warnings:
malloc() of 128 with the following non-sleepablelocks held:

I'm willing to work on this myself if someone can give me a pointer to
technical docs describing how things are supposed to work.
I have not yet attempted to use the tl0 interface since I also have an
fxp in the system, but I do plan on using it later.
Here's the complete dmesg with warnings intact:
