That's a (known) misleading error message - it's no longer necessarily
an error internal to the kernel, but can be caused by invalid
parameters being supplied to a device-mapper target.

See previous messages on this list, WHATS_NEW file, example.conf,
lvm.conf man page etc.
e.g. Use a config file containing:
log {
file='/tmp/lvm2.log'
level=7
overwrite=0
}
And remember to say exactly which kernel patches you applied.
[The device-mapper version number is not sufficient because
people have produced patches that don't update it.]
For example, a set of patches before Xmas had a bug that is
known to stop all snapshots from working.
To see if you have that logic bug, check dm-snapshot.c
a little after line 400 - it should have:
if (persistent != 'P' && persistent != 'N') {
^^
ti->error = "Persistent flag is not P or N";
