I have updated the CWM to v 188.8.131.52, you can view the CyanogenMod recovery repository for more in depth changes. The important one is a buffer overflow fix for dedupe backups, which I am hoping will help with reboots during dedupe backups.
I also changed the kernel I used from the cm9 one to the cm7 one that has been used in most previous recoveries. Hope that will eliminate some of the issues.
USB storage still doesn't work on this. I am working on it!!
