So, I was all happy and all with 4.11, and it still works fine.
S3 sleep just works, hibernate just works.
And then 4.12 came, and S3 sleep would not work reliably
4.13 came, same thing
4.14, again, same thing :(

Currently when I put the laptop to sleep, it sometimes, but just
sometimes, keeps the thinkpad light in a slow pulsing light as if it
were still in sleep mode, and just never wakes up.

Sadly, this is crappy to bisect since it's not reliably reproducible.

Before I go through that pain, are there any suggestions or ideas I
should try?

Thanks,
Marc
