Binary package hint: cryptsetup

I have setup LUKS to have my encrypted home directory auto mounted when logging in.

After upgrading to Karmic, I noticed that from time to time my home dir would not get mounted. Recently, this has become very annoying: I have to try several time before cryptsetup succeeds in opening my home partition.
Below a typical login session:

If I log with another user (having non-encrypted home dir) and try to unlock manually the partition with cryptsetup, I have to try several times before eventually succeeding (in the example below, I succeeded at 5th attempt):

root@ciccetto:~# cryptsetup luksOpen /dev/sda7 _dev_sda7

Command successful.
