End Kernel Panic: VFS: unable to mount

Greetings,

I had a bit of a scare today. My shows playing with Plex kept stopping at random. I restarted Plex, then restarted my router to no avail. The last thing to be restarted was OMV. However, it never came back up. I received the 'end kernel panic - not syncing: VFS: Unable to mount" message. I've done a recent upgrade but I can't tell you if I was upgraded to the latest version provided on 25 May.
I have the following for boot options:
3.16-0.bpo.2-amd64
"" recovery mode
3.2.0-4.amd64
"" recovery mode
2.6.32-5-amd64
"" recover mode

For giggles, I chose 3.2 non recovery and I appear to be running now. When I tried to login to the admin page, I got the scrunched page and can't see anything in the right pane.

Any thoughts on why this happened and why the boot option I selected instead of the default would be appreciated. The posts I reviewed were a couple years old and referred to a clean install. This one isn't.

Can someone please take another look at this? Any time that I need to restart, I have to hook up a monitor and select 3.2.0 from the GRUB menu before my NAS will boot completely.
