Public bug reported:

My laptop repeatedly kernel panics after a botched "return from suspend"
in my Samsung 900X laptop using (K)ubuntu 16.04.

Booting into 4.2.0-38-generic kernel seems to work fine.

Up until this point 4.2 and four different 4.4 kernels functioned
properly 90% of the time. Even then, roughly one-in-ten 'resumes from
suspend' would panic, usually with blinking caps-lock LED. Cold-shutdown
and restart would bring the system back up with little to no issue. This
time was different, not sure why.

Going through DebuggingKernelSuspend
(https://wiki.ubuntu.com/DebuggingKernelSuspend)

DID THIS: Shutting the lid of your laptop, which is set to suspend on close.
DID THIS: Pressed the power button
GOT THIS: kernel panic-- no blinking caps lock, just a single unblinking 
half-cursor at the top-left of the screen


cat's of appropriate files are attached. If more is needed I am more than happy 
to oblige.
