This isn't a regression.
I have LVM working with hibernate w/o any problems (w/ ext3). If there were a problem it wouldn't be with LVM but with device-mapper, and I doubt there's a problem with either. The stack trace shows that you're within XFS code (but it's likely its hibernate).
You can easily check whether its LVM/device-mapper:
1) check "dmsetup table" - it should be the same before hibernating and after resuming.
2) read directly from the LV - ie, "dd if=/dev/mapper/video_vg-video_lv of=/dev/null bs=10M count=200".
If dmsetup shows the same info and you can read directly from the LV I doubt it would be a LVM/device-mapper problem.
