Hmm, I have something that's possibly related - the USB bus locks up 
after a while. It doesn't seem to be load related - I can't reliably 
provoke it by transferring lots of data so it seems to be totally 
random, it happens even when I only use a keyboard, usually within an 
hours.

I'm using a CMD OHCI card in a UMAX S900 running NetBSD 2.0G from 
yesterday - this happened with all 2.0 versions I tried (started with 
2.0F and updated pretty often) No idea about 1.6.2, didn't use it heavy 
enough to be sure about it, but it didn't seem to have this problem.

have fun
