I expect you'll find it's ext2-reservations-bring-ext2-reservations-code-in-line-with-latest-ext3.patch which gets stuck in a loop there for me too: back it out and all seems fine. It's not obvious which part of the patch is to blame: mostly it's cleanup, but a few variables do change size: I'm currently narrowing down to where a fix is needed.
