My system: Fedora23 spin Scientific (KDE)
* I did a dnf update 2016/12/06 where kernel was updated
* Had problems with connecting cellphone so I uninstalled four libraries for mtp (media transfer protocol) that I thought conflicted. Should have used command remove, but no difference from what I understand. This uninstalled/erased in total 81 packages. Reboot.
dnf erase libmtp simple-mtpfs gvfs-mtpf kio-mtpfs
After restart I enter the passphrase for my luks-encrypted ssd (/dev/sda) with boot, kernel etc. I come to the fedora login window which has changed appearence and when I type my password, no message of wrong password, no response. This happens for the last kernel 4.8.11-100.fc23.x86_64. Rebooting, the same happens for my two previous kernels 4.8.10-100.fc23.x86_64 and 4.7.10-100.fc23.x86_64
I also have a rescue kernel that I am trying to boot but fail to enter the passphrase. It reaches the emergency stop prompt after a little while and I manage to read some logs.

Failed to start Cryptography Setup for luks-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Failure for several functions due to dependency
I boot with a liveCD
From here I can open the ssd with passphrase.
The hdd I get the following error messages
* Wrong passphrase:
An error occurred while accessing 'Home', the system responded: The requested operation has failed: Error unlocking /dev/sdb2: Command-line `cryptsetup luksOpen "/dev/sdb2" " luks-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" ' exited with non-zero exit status 2: No key available with this passphrase.
* Correct passphrase:

Added a new passphrase to my ssd and hdd disks to avoid errors from deafult english keyboard(usually swedish). Booting to latest kernel again and get passphrase question also for hdd-var at startup, this has not happened before. Stops at the same point as before - Failed to start Security Auditing Services and gets emergency mode prompt. But now I can access my hdd to save some files I hadn't backed up, great! From the logs I read, see file for full info.

I read some posts and at booting up again with the latest kernel I get passed the ssd passphrase and the fedora login window appears as before, non/responsive, but I use Ctrl-Alt-F2 to enter a pseudo-prompt and I can login in to the system and do a proper backup. I can now access the system, like the dnf history, but just through the prompt no KDE desktop environment.
What would be the wise thing to do?
* Undo update
* Undo erase of mtp packages (which would mean install the packages again?!)
* Try to do a new dnf update (I haven't found any bug reports on my latest kernel...)
* Try to fix the desktop environment that has been affected somewhere outside all three kernels.
* Since F23 is soon unsupported, I will have to do an upgrade soon anyway, but would like to understand the problem I had for some days now...
