A friend of mine just ran into this and we spent some time debugging it. Long story short, I stumbled onto an lkml thread that seemed related [1].
Something tytso said in his first reply [2], and the fact that the root fs was ext4, led me to try: echo 4 > /sys/fs/ext4/sda1/max_writeback_mb_bump and suddenly the dpkg that had been stuck for at least 30 minutes started doing things again. I wish we had figured it out before giving up on the dpkg that had been stuck since January and forcing a reboot.
