I guess I'll keep an eye out for this problem if/when I get 8 running; 
if I hit anything similar, perhaps I can add some bisecting assistance.

OK, I will see about this later in the week; one thing I noticed which 
may/may not be directly related: the kernel seems to try using the hub 
*before* loading the firmware file - if I have the hub plugged in at 
boot, I still get the timeouts and it never actually loads the 
firmware.  Let me know if there's any specific action I should take with 
respect to this; otherwise, I'll just get a debug kernel up later in the 
week and see what I can see.

Great; I'll try a newer -current kernel here as well.

Thanks for the response!
