No advice, but I experienced this exact problem last night. I'm running a Tyan
Tiger LE motherboard, 2x PIII 733, 512M RAM and various other bits. It hangs
in the exact same spot as yours does, which isn't surprising considering both
motherboards use essentially the same chipset.

This machine has ran with 4.x in the past, as well as an older 5-CURRENT, but
I don't have timeframes for either.

I'm fairly certain it's not a hardware problem. Google turns up a few other
people with the same problem, so I don't think we're alone. I was going to
fire off an e-mail to the lists today, but figured it would be best just to
chime in with a "me too" since you've already got one in.
