FINALLY had a chance to flash Gingersense 3.5 today. Its a pretty good ROM but I was getting quite a few FC's..and not trivial things like apps, I mean Superuser and a couple others that seemed pretty important to the overall stability.
It also had quite a bit of lag and big time battery drain though to be fair I didn't really give it a chance to settle out (I usually like to give ROMs 3 days or so to really level out)
Also my WIFI wouldn't work no matter what I did...re-boot, fix permission, and different kernel but all to no avail...no WIFI for me.
I did make a nandroid of it though so when Nils puts out an update I can just flashover it and maybe it'll get better with less lag.
Edit: Well I'm an idiot. Went back to XDA and re-read the original 3.5 thread and Nils lays out how to alleviate most of these types of problems. It'll have to wait till tomorrow though as it seems a bit involved.
