[picking a recent e1000 commit]

Hi Jack,

I'm getting the following panic on head r200376 on my HP DC7800 work 
desktop:

mtx_lock() of spin mutex &dev_spec->swflag_mutex @ 
/usr/src/sys/dev/e1000/e1000_ich8lan.c:651

I don't experience the panic with an 8.0-RELEASE kernel.

Anything obviously wrong with that line of code as far as you're 
concerned, or do I need to dig some more detail out? Debugging with this 
system is painful, hence the initial hand transcribed minimal detail, 
but if you need more info I'll try figure out how to get you what you need.

Cheers,
Lawrence
