I have 2 laptops - one is an 
   ASUS ZenBook UX535LI_UX535LI
the other is :
   MSI Katana GF66 11UE

At random times I get kernel crashes, but mostly on reboot while its shutting
down.
I installed the debug kernel on the ASUS along with kdump and cockpit hoping to
get more detailed information but, of course, then it wont crash.
This doesn't happen every reboot, but it's often enough to be annoying and its
happening across multiple kernels. Occasionally, I get a crash while I am
surfing the web or just moving the mouse.
ok, why do i think its a kernel crash? Because the system hangs and the caps
lock led flashes on & off rapidly for about 90 seconds and then the laptop
resets. Am I right that this indicates a kernel crash?
Not sure where to go from here.
