Hello,
On a T440s (intel graphic + nvidia) with ubuntu 16.04, I experience

with linux 4.6 from kernel-ppa.

Meanwhile, if you have any hints, whether what to debug or test, it
would be very much appreciated.

It seems that the system is not always able to write something in logs when
this occurs :

Hi,
For T440s or T440p owners, I tried the latest stabke kernel (4.7)
directly from kernel.org.
I still get random freezes on resuming from hibernate (suspend to ram is
not impacted).
Most of the time, the only trace remaining in logs is one line full of
"@^@^@^@^@^@^@".

Hi again,
I finally found out the cause of these random hibernate/resume freezes.
My swap partition is a logical volume which itself lies on a luks
