Public bug reported:
I have a Lenovo X1 Carbon Gen2. It as the adaptive row of keys that
change from function keys to volume, etc when you toggle the function
key. It's always worked fine but with this kernel, after a few
sleep/resumes, the entire row will go black. If I reboot it will return
to normal. dmesg throws a bunch of these..
