[AT&T Samsung Galaxy S II Skyrocket SGH-I727] m4570d0n:
Good post. Are you using CWMR 5.5.0.4? If so, there is apparently a known bug that if there is a file name that is "too long" it can cause the backup to freeze. If you're using the CWMR Touch from this thread, there is a workaround posted in there that worked for me. Create an empty file called ".hidenandroidprogress" and place it in /sdcard/clockworkmod.

touch /sdcard/clockworkmod/.hidenandroidprogress

or for external SD,

touch /sdcard/external_sd/clockworkmod/.hidenandroidprogress

Also, I mentioned this in another thread, but I have not been satisfied with the BusyBox or su sources that I've seen in the dev section here. Apparently there are minimal versions and full versions of BusyBox, and the one you get from the BusyBox app in the market seems to be the minimal version. Additionally, there are a couple issues with SuperUser for ICS.

However, wraithdu has provided some awesome modded su binaries for ICS and BusyBox in the V6 Supercharger thread, as well as install scripts and/or CWM flashable install zips. I used these, and have run into a lot less issues since then.

BusyBox instal scripts and CWM flashable zips are in the OP here:

I have a couple questions/comments regarding this ROM.

#1 - I switched over from NexusMod Beta 3 this morning, and when I first booted up I had some stupid Cingular WAP apn settings. I had to go in and manually change it to the correct ATT pta apn (rest to default apn just resets to this cingular apn) in order to get mobile data up and running again. Any idea why that is?

#2 - When I try to fix permissions with ROM Manager, it get's most of the way through, and then just freezes. I can back out of it and the phone keeps running fine, but I won't complete the process whenever I try to do this. I haven't run into this issue before and not sure what the problem is here.

#3 - On the NexusMod ROM, you don't get the "Android is upgrading. Optimizing apps 1 of whatever" screen whenever you boot up. I'm not sure what the point of it is, but the phone ran just fine without it on the NexusMod. Just throught I would throw that out there as a possible change for a future update.

Also, this is not specific to this ROM, and I'm not sure if it's even specific to mohan_kr's kernel, or just the linux 3.0 kernel in general, but my logcat is constantly filling up with this error at all times:
