This lts-trusty test kernel is not booting when installed on 12.04.5.
There are multiple events like this being recorded on the serial:
udevd[275]: timeout: killing '/sbin/modprobe -bv
vmbus:394f16571591784eab55382f3bd5422d' [380]
udevd[246]: timeout: killing '/sbin/modprobe -bv
vmbus:e7f4a0a945
I built a Trusty test kernel. Sorry for the delay, it required
backporting 20 other commits.
The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1454892/trusty/
Can you test this kernel and see if it resolves this bug?
Thanks in advance!

Ah, I thought the 3.16 kernel was no longer updated except CVEs as
utopic was only used for 14.04.2 and that was deprecated to vivid for
14.04.3. In my documentation I encourage users on 12.04 to run lts-
trusty, 14.04 to run lts-vivid, and in some cases I even advise some
customers to move to lts-
The test kernel in comment #30 is for the utopic HWE kernel in trusty.
I'll also build a Trusty HWE kernel for Precise and post it shortly.
