Try using wildestpixel's modified BB. This is the issue that first prompted him to apply his tweaks to Pete's nightly. I'm using it now and it's very stable and truly bug less. just Google wildestpixel to get to his website. you can find links to download there. Hope this helps!

Unfortunately, the Matr1x kernel is very unstable on my phone and I rather keep the kernel as close to stock ICS as possible.
I'll wait and hopefully Pete will have a fix for this issue soon.
