Christopher,
I have some more information. As stated in the initial bug report, the latest
kernel (3.13.0-48-generic) with KMS enabled gets me to the password prompt for
decrypting my root, and the graphics appear to be ok, but the keyboard/mouse do

On a hunch, I rebooted with
descending3rds, the next step is to fully commit bisect from kernel 3.5
to 3.13 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following
Christopher,
I have tested the latest mainline kernel 4.0-rc7 which includes the usb hid

Christopher,
According to my computer (Mac side) the bios is in fact already the latest
available for the model iMac4,1
(not iMac14,1 as I suspect you probably had in mind). Thus, I am afraid there
is no more information I can give
at this point. Therefore I am marking this report Status
descending3rds, could you please test the latest upstream kernel
available from the very top line at the top of the page (the release
names are irrelevant for testing, and please do not test the daily
folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will
allow additional
