Have anyone else noticed this?
If I boot any of the recent 4.7 kernels, I can immediately suspend my laptop without incident. If I leave the system up for some reasonable amount of time, then everytime I try to suspend, it fails. journalctl shows that 2 Mate daemons refuse to Freeze:
Here is just one exert from my journal:

Oct 26 12:43:04 kjclap4 kernel: video LNXVIDEO:01: Restoring backlight state
Can anyone shed some light on this? It continues through kernel 4.7.9. (I have not yet booted 4.7.10.)
If I try and suspend, it fails, and restores the kernel to a fully running state, usually on battery, and usually with the laptop fan continuing to run, expelling heat into my laptop case if I don't notice it!
