Public bug reported:
Following a recent upgrade of Ubuntu server "Lucid" to 2.6.32-24 my
normal daily backup script crashes the system when it tries to create a
new logical volume to use as a snapshot. The normal "logical volume
created" message does not appear and the script hangs.
While the system seems to respond to pings and TCP opens, the server
processes ( apache, postfix, samba, webmin) do not respond.
SSH and the serial console accept the login but don't prompt for the
password.
System does not respond to power switch either so the only way to
restart it is to do a hard power off.
Symptoms have been repeated by running the backup script manually from
both console and ssh logins as well.
Syslog output at the time of the backup was as follows:
Aug 13 00:05:01 zaphod CRON[2620]: (root) CMD (~tjon/bin/newbackup #Daily
backup script)
Aug 13 00:05:01 zaphod kernel: [55215.128950] RPC: Registered udp transport
module.

backchannel transport module.
Aug 13 00:05:01 zaphod kernel: [55215.261954] svc: failed to register lockdv1
RPC service (errno 97).
If I restart the system and manually select 2.6.32-23-generic from the
GRUB boot menu the bug disappears.
