I'm still trying to get my second Chili back up and reliable.  Right now, it stops talking to cgminer/bfgminer after 2-8 minutes and needs to be powered off/on and the miner restarted to resume mining.  Rinse and repeat.  I've posted the errors earlier (https://bitcointalk.org/index.php?topic=304250.msg4557778#msg4557778).  Anyone have any ideas/suggestions?

So far, I've tried: reflashing the the 1.1v-limited firmware, reflowing the FTDI chip, reseating a nearby small SMD capacitor that might have gotten dislodged, but so far still unstable.  Before I had the pin 5-6 shorting mishap (hit an adjacent pin at the same time during a reset, trashing my FTDI chip), it was pretty solid, though I did have to reset it about once a day.  Replaced the FTDI chip with a new one, programmed it (thanks Mr. Teal!), and was back hashing, but never stable or even usable.

Help?
