Hello,

I asked here about a week ago for help with debugging a random lock I've
been experiencing. With the help of Mr. Owens, I seem to have gotten a
bit further. (Long winded way of saying, "Sorry about the messy
looking, clueless debugging.")

I'm running 2.4.2 + KDB 1.8 on my SMP machine (2xp3-600). I have a
serial console connected to my box. It looks like things might be
locking up in the EMU10k1 driver. Anyone else? Is there any further
info I can provide to someone who might be working on this?

Thanks,
pete
