That sounds like wonky hardware

If it launches grub the disk is fine (Grub is loaded off the disk) and I
assume the laptop has one disk.

The EHCI error is from USB so perhaps points to a USB problem.

If a soft reboot fails but a hard reboot (reset button held down) works
I'd suspect its something hardware related not getting properly
shutdown/restarting etc.
For diagnostics boot with "verbose norhgb" that should spew lots of
messages and not hide it all with the graphical stuff - meaning you can
actually see what is going on. See where that hangs.
You could also see if reboot=acpi helps. That changes the way the reboot
is done and might be better for modern machines. Len Brown is currently
collecting data on making this a default so your box may be a useful data
point.
