Public bug reported: Binary package hint: libpam-mount
Since I upgraded to Karmic, I noticed the weird fact that my two auto- mounted LUKS-encrypted partitions randomly seemed to disappear from mtab - I had to manually mount them again to use them. I've been using them for several years with all ubuntus so far, never had a problem until now. These partitions are automatically mounted on login via pam_mount. These are the entries in pam_mount.conf.xml: <volume fstype="crypt" path="/dev/sda3" mountpoint="/media/sda3" options="cipher=aes" /> <volume fstype="crypt" path="/dev/sda5" mountpoint="/media/sda5" options="cipher=aes" /> After digging in the logs, I've found that there is some sort of a cron job trying to unmount my two partitions and running every 60 minutes. If the partitions are busy then they survive; if they are not busy, then they are umounted (very weird !!!!!) >From my auth.log I see this every hour: Nov 15 11:17:01 nahuatl CRON[1230]: pam_unix(cron:session): session opened for user root by (uid=0) Nov 15 11:17:01 nahuatl CRON[1230]: pam_mount(pam_mount.c:516): warning: could not obtain password interactively either Nov 15 11:17:01 nahuatl CRON[1230]: pam_unix(cron:session): session closed for user root Nov 15 11:17:01 nahuatl CRON[1230]: pam_mount(mount.c:67): umount messages: Nov 15 11:17:01 nahuatl CRON[1230]: pam_mount(mount.c:71): umount: /media/sda5: device is busy.

A hint or workaround on how to stop this CRON thing from trying to unmount my drives would be greatly appreciated.
