When I tried to install Raspbian Jessie, on the first boot my Raspberry Pi 2 got stuck on:
This is a link to a list of SD card's.
For what its worth I had this exact same problem. I tried swapping all peripherals, two different Pi 2 Model B's, different power supplies and two different cards. These combinations had all worked fine with Wheezy but didn't play ball when it came to running Jessie - both an upgraded version and a clean downloaded image.
I came across this post and although I had tried two different cards they were both the same make/model (Delkin Micro SDHC 8GB class 10). I also noticed that the green ACT LED stayed on solidly once the boot process hung. So the final thing I tried was swapping in a third SD card from a different manufacturer - an SanDisk Ultra I had previously used for a GoPro. This booted up first time! It would therefore seem that the newer Raspbian images are much more sensitive to the type of card used.
