in our case (different config&c) the usb is simply dead (no panic): it 
won't recognize any usb devices attached to it. in my case, with my 
beagle, i boot off the sd only (i leave the usb disk for my omap4) but 
yes is still a fatal IMO since these boards have evreyrhing attached to 
the usb bus.

the problem with omap3 is that no one is actually using it for real in 
our community (everyone moved to omap4) and people that do some testing 
use the emulated beagle via qemu (that didn't show this bug), i stumbled 
on this bug last week when i tried Q by myself.
