4.9 Boot Hang when USB Devices Attached

[Joe Kelsey]

I have a system running

FreeBSD zircon.zircon.seattle.wa.us 4.9-PRERELEASE FreeBSD 
4.9-PRERELEASE #20: Fri Sep 19 12:55:28 PDT 2003

When I upgraded to fix the OpenSSH problems, the system started hanging 
at boot time right after the USB/OHCI messages whenever I had devices 
plugged into the USB ports (mainly a USB mouse).  Now, in order to boot, 
I have to unplug the mouse and wait for the system to pass the USB part 
of boot before replugging.

Due to lack of attention on my part, I had previously built a kernel 
around 25 August which also exhibited this same symptom, but I had never 
actually booted it.  So, when I reverted to kernel.old, I got the same 
hang.  I had an old GENERIC kernel that I booted from to experiment with 
solving the problems.

It seems a little more than inconvenient to have to unplug and replug 
USB devices in order to boot.  Does anyone have any insight to offer?

dmesg output attached.
