Hello tebclause,

yes, the symptoms you describe are exactly bug 36664 

Next time please _comment_ on the bug since you already suspected the correct
one (bug 36664) instead of creating a dupe.

See here:
http://cloud-images.ubuntu.com/releases/12.04.2/release/unpacked/release_notes.txt

The Linux kernel was updated from 3.2.0.63.75 [3] to 3.2.0.64.76 [4]
...
  * x86-64, modify_ldt: Ban 16-bit segments on 64-bit kernels
    - LP: #1319885
--- quote ---

Wine was deliberately broken to fix a potential security issue.

"a few 16-bit apps" ... sure.
A lot of 32-bit installers still carry 16-bit (legacy) parts.

Same breakage happened with Fedora distro I use.

There is a temp patch, making it a runtime option:

https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/commit/?id=fa81511bb0bbb2b1aace3695ce869da9762624ff

and some work to fix it properly: https://lkml.org/lkml/2014/5/4/376

It might take some time until distros backport this too.
Until then you are stuck with booting older kernels.

Regards
