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 "@^@^@^@^@^@^@". Considering thus that there is no fix upstream, I went downstream and installed the longterm kernel 3.16.36 (still from kernel.org). I think it is the kernel version currently used by ubuntu 14.04 It seems to solve this bug. I say "it seems" because as the freezes occurs randomly, I could just have luck. Nevertheless, I was able to hibernate/resume 4 times, one after the other, without any freezes or kernel faults, which did never happen before. I will confirm later if freezes do not happen anymore. You can try also, possibly with a higher kernel version, so that we could identify which version change is responsible for this bug.
