Comment 4 for bug 954810

I installed opscode chef server, etc. et all
Changed my mind when it looked like there were more dependencies than I expect.
When chef server was purged the question of whether or not to keep cryptsetup was a question and I said "no"
shortly after that I thought that perhaps full disk encryption would break so installed it again
(all of this after an upgrade from the 3.5.0-23 kernel to 3.5.0-25

in short, after a reboot for the upgrade ... FDE choked and didn't ask for the passphrase.
I tried the 3.5.0-24 kernel and that didn't either
then, I booted 3.5.0-23 and it worked again.

not entirely sure what happened.
