Suspend does not work on the X220t
On my Lenovo X220t, suspend to RAM does not work.
It seems to go to suspend correctly, and the power LED turns of after a few moments.
Now, the laptop is in a state where I can not start it.
The power button does not work, and the only way to get to a working state is removing the battery.
Of course, this defeats the sense of suspend to RAM.
Tested suspending with Windows 10 and Arch Linux (systemctl suspend).
config and EHCI log atttached.
