Version: 2.4.27-6
Severity: normal

Hi!

I use EVMS snapshots on my server.  When I reset snapshots, sometimes
system crashes in dm_snapshot.c. Sorry I can't provide more information,
because crash dump was only on the screen and the server was restarted
after crash. When next crash occures I'll send you more detailed
information. My disk configuration is below.
Please see the last line about /dev/evms/var_snap - system crashed when this
snapshot was resetted.

jk@forward:~% echo "query:objects:query:volumes" | sudo evms

EVMS Command Line Interpreter Version 2.5.1

Snapshot: Snapshot object var_snap discovered in full/disabled state.  Use the "Reset" function to reset the snapshot to the
current state of /dev/evms/var
