So, I wiped cache/davlik 3 times each, wiped data/factory reset a couple times, and ran DARKSIDE as well just to be sure. Flashed ROM and rebooted. It took several minutes, which is to be expected, but then the boot animation stopped and it came to a black screen with the launcher selection menu. I let it sit for several minutes. For some reason the screen never turned off during this time. When I finally decided to select a launcher and go, nothing happened. It was frozen. Short press of the power button would not turn off screen, and the phone did not respond to any screen touch input or pressing any buttons. I pulled the battery and then rebooted. Took about 5-10 seconds to boot up and everything seems to be running just fine.
The exact thing happens to me. I reflashed and flashed the ics modem also and everything seems OK so far.
