[linux-lvm] Linux 2.4.16+SMP+Ext3+LVM snapshots

So I'm building a file server with a 3ware raid card (6800, maybe replaced
with a 7800).
This is a dual-1.2 Athlon running 2.4.16 with LVM sitting below our ~700GB
ext3 data partition. At first, we used the lvm support included in the
kernel.
After some copying, I tested
lvcreate -s -l 200 -n test1 /dev/vol0/cobra
The snapshot was corrupt. Known problem. Fair enough.
So I grabbed lvm 1.0.1 (released a couple days ago). I patched the kernel
with the new lvm and the VFS-lock patch for 2.4.11. There were quite a
few offsets, but it otherwise applied cleanly.
I started a big cp off an NFS mount and ran
lvcreate -s -l 200 -n test1 /dev/vol0/cobra
The cp and lvcreate deadlocked. Both are frozen in D state and they're
not coming out.
Snapshots were the big reason for us to use LVM, so this is not good.
Help!
