The current status of the FC2 test1 release is that this kernel bug needs
fixing, and then we should be good to go. Any help fixing the problem
would be greatly appreciated!
Friends help you move. Real friends help you move bodies.

AFAIK, this is the first time we've tried it under 2.6.
Due to a variety of circumstances, yes.
Attached is a simple test program that can be used in reproducing.
1) Copy some image you can loopback mount to /tmp/loop.img (doesn't
matter what, you can even just dd /dev/zero and mke2fs it)
2) losetup /dev/loop0 /tmp/loop.img
3) mount /dev/loop0 /mnt/tmp -o loop,ro
4) cp /tmp/loop.img /tmp/new.img
5) ./testchangeloop /dev/loop0 /tmp/new.img
And watch it hang
