Hi

Also look at:

dm-io crashes when signal is sent:
http://people.redhat.com/mpatocka/patches/kernel/misc/2.6.29-rc8/dm-dmio-fix-signal-crash.patch

that partial-read dm-raid1 + dm-multipath crash:
http://people.redhat.com/mpatocka/patches/kernel/misc/2.6.29-rc8/dm-record-bio-vector.patch
http://people.redhat.com/mpatocka/patches/kernel/misc/2.6.29-rc8/dm-raid1-read-record-slab.patch

crash or data corruption in snapshots (callbacks are called concurrently 
and shouldn't be):
http://people.redhat.com/mpatocka/patches/kernel/misc/2.6.29-rc8/dm-kcopyd-fix.patch

failure to check pending exception after we dropped a lock:
http://people.redhat.com/mpatocka/patches/kernel/misc/2.6.29-rc8/dm-snap-break-__find_pending_exception.patch
http://people.redhat.com/mpatocka/patches/kernel/misc/2.6.29-rc8/dm-snap-move-allocation-to-the-caller.patch
http://people.redhat.com/mpatocka/patches/kernel/misc/2.6.29-rc8/dm-snap-check-complete-exceptions.patch

--- all the patches fix crashes or data corruptions.

--- all these patches except the first one were already committed to RHEL 
4.8, so you should put them upstream, at least for testing.
