i was able to capture the dmesg's to another lvm logical volume disk
despite i/o beeing blocked on the lvm locical volume that i was trying
to take a snapshot of, like so

sudo lvcreate -s -n data.snap -l100%FREE /dev/babar/data
sudo lvcreate -s -n home.snap -l100%FREE /dev/babar/home

i have 225 lvm physical extents free at the end of the disk and the
snapshots used to work like a charm in linux-2.6.32-22 (and -23 as well,
i think)

judging from the diff from -22 to -24 it could be something about

btw... why is the linux_2.6.32-23.37.diff.gz not available in
archive.ubuntu.com ???
