Comment 6 for bug 1506139

OK, I am back at my home machine: The problem occured again, the machine destroyed again luks on /dev/sda2.

Furthermore, I have another problem: When doing a regular boot, but boot process hangs after systemd listed the names of several services (in most cases networking.service is the last printed, which is not quite useful, since these are, as I understand it, finished services, not the once that cause trouble. I did not yet find a way to make that damned systemd tell what it's doing.

Strange enough, the machine boots without problems if I choose there recovery mode, choose to aktive network from the menu, and then go on, so it works when recovery mode is part of the boot chain. I guess Ubuntu will have lots of fun with that systemd.

sudo blkid (sda2 currently damaged again)

(I've replaced the serial number of my disk with *********)

.
I'll now repair the partition as described, reboot and come again.
