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:
exclusive sleep mutex tl0 (network driver) r = 0 (0xc4017aa8) locked @ /usr/src/5-current/src/sys/pci/if_tl.c:1146
malloc() of "PROC" with the following non-sleepablelocks held:
exclusive sleep mutex tl0 (network driver) r = 0 (0xc4017aa8) locked @ /usr/src/5-current/src/sys/pci/if_tl.c:1146
lock order reversal

Stack backtrace:

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:
