Secure boot won't work with the proprietary nvidia drivers. At least not
without substantial effort (generate your own signing key, sign the dkms
generated modules with this, get key trusted by uefi) since the kernel
modules compiled are unsigned.
If it looks like a USB issue then disconnect all USB devices on
starting
to see how far it gets.
You'll probably want to remove rhgb and quiet from the kernel arguments
whilst debugging.
There are no USB devices connected to the laptop; both rhgb and quiet are
also removed, I will see if I can get more information with kernel 4.3.3
debugger.
Seeing as it's in testing it'd be useful to have a bug filed
and this
commented on the bohdi kernel update page.
I will do that thanks.
