Comment 12 for bug 1384041

Bad news.

 v3.18-rc2-utopic screws things up completely and the system doesn't boot.

The symptoms are as follows:
- the initramdisk doesn't show the password prompt to unlock the full disk encryption.
- the external usb keyboard doesn't work (i.e. I can't use ESC to hide the splash screen on the external keyboard but I can use ESC on the internal keyboard. However it is not a complete USB outage since both, the keyboard and mouse are showing lights. The external keyboard does work during grub though)
- after hiding the splash screen it tells me something about not finding any volume groups (not really surprising if it skips the disc encryption...)

I tried to run dpkg -i on the three kernel packages again to re-generate the initramdisk and look for errors. I didn't see any relevant messages and it still failed to boot. The kernel packages I used were

linux-headers-3.18.0-031800rc2_3.18.0-031800rc2.201410262035_all.deb
linux-headers-3.18.0-031800rc2-generic_3.18.0-031800rc2.201410262035_amd64.deb
linux-image-3.18.0-031800rc2-generic_3.18.0-031800rc2.201410262035_amd64.deb

I dare say, there is another issue at work here than the one we were dealing with so far.
