Can't do any further testing while at work but was getting some really odd behavior out of Franco combined with the latest test build of DU (7/13).
1. As soon as I added Franco r57 to the new DU test build, I started boot looping. Clean flash didn't help. Strangely enough, restoring a nandroid of the previous version didn't help. Downgrading to r56 didn't help. Was fine with the DU stock kernel (not furnace). What finally seemed to fix it was flushing all Franco settings and resetting them manually.
Theory for #1: I think I may have upped the undervolting from -50Mv to -75Mv some time back and it seemed okay. I suspect something changed and it was no longer okay. Keeping it at -50Mv and, so far okay.
2. Going to reset up all the settings brought up another odd problem. With the latest FKU (which had just been updated maybe a day or two ago), whenever I went to try and change a governor setting, it would only bring up the CPU frequency screen. Rebooting didn't help. Uninstalling and reinstalling didn't help. I finally used TB to install and older version of FKU and everything behaved fine and I was able to make my settings. I will try reinstalling the update later tonight with my settings already locked in and see if I see the same thing or if it was some fluke. Anyone seeing or reporting anything like this? If it happens again tonight, I'll report it to Franco-- or there may be already be a fix posted by then.

Just weird.
