 i recently patched this system's kernel and rebooted it, it only
 took 6 or 7 power cycles to work this time (i really really need
 to replace this system), and then another power outage lead it
 two dumps of the rx descriptors when it has hung.
 
 both times the rge(4) hung about 1h after booting.
 
 unfortunately, AFAICT, all 1024 are currently "owned by the
 hardware", and appear to be ready to go, both times.  ie, there
 is no indication what is wrong here at all.
 
 i don't know enough about how this sort of h/w works to really
 judge what is happening here.
