Hello Devin,

I switched to 1.10 after having problems with the 1.20 firmware. I
swapped the files back yesterday, and tried running with the current
drivers and the 1.20 firmware after a cold boot. You are right. The 1.20
firmware is significantly better than 1.10. 

A one point the 1.20 firmware ran for almost 2 hours before I noticed
problems. I shut down and restarted a couple of times after that, and
got errors within minutes.

The number the firmware download fails at changed each time but the
"with -110" was the same.

Best Wishes,
Rob
