I'm more of a lurker, but definitely wanted to post in this thread to confirm my positive experience with this kernel.
I've been running the RC's of version 0.1.5 on AOKP ICS Build 37 and have been impressed at how much more stable the phone is, as opposed to with the stock kernel. I certainly don't mean to knock the previous keepers of the AOKP Supersonic ROMs at all, but the builds simply don't seem to have been optimized for our phone. Having said that, the Mason kernel doesn't make the AOKP ICS build perfect, but I'm now getting soft reboots only rarely, no hard reboots, and by far the best battery life I've experienced on this phone.
Just wanted to share my experience. If one is looking around at third party kernels to try, this is definitely a great option.
