AO-92 has started to change its behavior after a number of weeks powered on.  In particular, the IHU has come back on and switched to safe mode.  This is likely due to low voltage during eclipse when it should be drawing very little if no one uses it.  

N8MH also reports that he is turning off FalconSat's transmitter for a while due to low voltage.

The AMSAT Ops team is going to shut both down for a while in hopes they will recover.

AO-91 still seems to be ok!
